Solitary circuits The first letter identifies the circuit as: Solitary digital circuit T: Family circuits These are digital circuits related in their specifications and primarily designed to be mutually connected.
The first two letters identify the family. Quadruple in-line – For other variants the version letter has no fixed meaning, except the letter Z which stands for types with customised wiring. Digital circuit, GX-family; temperature range: Analogue circuit; temperature range: Former code First two letters: Plastic plug-in package Plastic packages are soldered on the side of the printed circuit board opposite to the case, the pins are vertically bent and fit into holes at an equal distance of 7.
The distance between the package and the printed circuit board is determined by shoulders see picture. After inserting the package into the printed circuit board two or more pins should be bent at an angle of app. Thus the package need not be held down while soldering. After bending the leads ver- tically the case is inserted into holes of.

The distance of the bend from the case may not be below. After inserting the case into the printed circuit board two or more leads should be bent at datasjeet angle of app. Thus the case need not be held down while soldering. The leads should be clipped before soldering. Iron or dip soldering may be applied. The maximum solder times are: The leads are connected to the printed circuit by iron soldering fz1h11 spot welding. Bending of the leads When bending, the leads must not be stressed between leads and case.
The minimum soldering distance from case must be at least 1. The minimum soldering distance Dip soldering J from case must be at least 1. Package 5 H 8 DIN and similar cases with 8, 10 and 12 pins The position of the case is arbitrary. The pins may be bent up to a minimum distance of 1. The pins should be clipped before soldering.
Warranty If incoming testing shows that the AQL Acceptable Quality Level figures stated are exceeded, the customer is entitled to refuse acceptance and demand replacement of the shipment re- ceived. AQL-figures The AQL-figures define the maximum number of defective components up to which a ship- ment received must be accepted.
Electrical defects Single AQL, gradual electrical defects 1. Defects affecting the function in a minor way electrical data too low or too high, noiss 6tc. Slight mechanical defects missing type-marking, marking difficult to identify, wrong dimensions, heavy stamping burs at the pins, bent pinsad 4: Catastrophic failures broken or cracked packages, wrong type-marking, wrong position of the package-nose datashwet marking of pin 1, pins not solderable.
Receiving quality The figures shown in the table are warranty-figures. Rejections Returned IC’s can be accepted only if the faulty samples are datsheet to the rejected delivery. The circuit is suited for AC- and batteryop- erated datasjeet.
An additionally available control voltage pin 12 permits control of a RF-pre- amplifier stage. Especially suited for radio receivers and the sound-IF units in TV sets. These circuits are applicable as limiter amplifiers, as controlled demodulators or modulators or as mixers with excellent suppression of the input frequency. The 22 nF capacitor be- tween pins 8 and 11, together with the integrated resistor R 30, constitutes the de-emphasis and may be reduced if required.
The distance of the peaks on the S-curve can be adjusted with the Q Vatasheet of the phase-shifting cir- cuit. Zero crossing corresponds to resonance frequency. The circuit is directly interchangeable with TBA A pin-compatible. Input impedance Operation at The integrated circuit TBA S is supplied in different groups. Parameter is the volume.
A decrease of 30 dB requires a resistor between pin 5 and ground with a resistance value depending on the group number as shown below.
The group number is imprinted on the plastic package. Group R 5 II 1. Simultaneous in and output for AF Function: When switching voltage applied the emitter follower, BCon datasheeg output is blocked and the buffer stage, BCis switched on. It includes a pre-emphasis to balance the de-emphasis at the AF-output.
P and N are differentiated only in the polarity of the control voltage for the tuner prestage: P and N datasheeh are able to control the PIN diode attenuators common today without additional transistors. Automatic mono-stereo switching and manual stereo-mono switching forced mono.
Driver for indicating lamp up to mA. A high level of integration as well as excellent characteristics fzh111 both amplifiers permit a universal application in battery and AC- operated receivers. Reference potential is V: The chip lay-out has been designed to ensure tight thermal coupling between all the transistors in each channel to minimize and equalize thermal drifts between channels.
Also, each channel follows an identical lay-out to ensure equal frequenc behaviour of the three channels. This integrated circuit has been designed to be driven from the TBA synchronous demodulator integrated circuit. Because of its low current consumption and of its internal stabilization the TCA is perfectly suited for battery operated portables, car and home radios either.
Selection TCA is selected in 2 groups as concerns the output voltage V 7: Function As you see in the circuit diagram the TCA comprises two control loops independent of each other which are working on the prestage and the IF stages.

By the AGC of prestage an ex- cellent large signal handling is obtained. A voltage of 2. The push-pull mixer is operating multiplicatavely. Thereby are resulting par- ticularly few harmonic mixing products and whistling points. The oscillator which is separated from the mixer is also apted excellently for short waves.
From AGC of the RF amplifier a vol- tage is derived for a tuning meter which is connectable directly. The symmetric composition of the circuit allows a high stability against oscillating and, at the same time, an AGC range of more than dB.
The bridge circuit of the mixer suppresses very well the RF frequencies. Thereby the otherwise feared tendency of oscillating at low frequencies of the range of medium waves is disappearing. V, is chosen so that a constant V 15 is obtained 50 mV PB. RF input voltage switching position 1 Signal to noise distance v. RF input voltage parameter is generator impedance switching position 1 40 j 4. Its wide supply voltage range allows manifold use. The amplifier has class-B push-pull output and is furnished in single-in-line package.
The integrated shutdown protects the IC from overheating. TDA contains a controlled RF pre and intermediate stage, a multi- plicative push-pull mixer with separate oscillator, controlled IF amplifier, full-wave de- modulator, active low pass, as well as an amplifier to directly feed a field-strength indicator instrument.
By means of its amplitude-controlled oscillator, the TDA is particularly suited for applications with varicap diodes. The circuit is balanced. J ‘ “10 OdBMV eff v. The TDA offers provisions for the feeding of an amplitude indicator, either positive or negative going mono-stereo voltage, AFT output push-pull-current output with automatic switch-off, squelch adjustable for more than 40 dB range of input signal and depending on detuning.
If pin 13 is grounded, both the field-strength- and the detunmg-dependent squelch are switched off. Pin connections Pin 1 Ground 2 Sensor input for AFT switch off 3 AFT switch off time constant 4 Low-pass capacitor for detuning-dependent AF switch off 5 AFT output push-pull output 6 Low-pass capacitor for suppression of switch off clicks in case of detuning and insufficient field strength 7 AF output emitter follower with constant-current source 8 Output of limiter amplifier.
The AF outputs are referred to ground and stabilized against hum of the supply voltage. It is used in time multiplex switch operation or frequency multiplex matrix operation. The lamp current is internally limited to max.
By means of the variable base width, this stereo decoder is best suited for car radios. With the switch St-Such stereo transmitters fzh111 be selected. By means of the input OP, slight frequency corrections can be done according to the following formula so that height reductions are balanced. Thus, cross-talking can be improved.
Voltage at pin 14 without colour sync signal with colour sync signal peak-to-peak value of 0. The scattering of the gain is re- duced datashdet a minimum, since it depends only from the scattering of the relationship between Y delay line end resistor and the resistor R g. The colour sync signal is not influenced by con- trast and saturation adjustment; it remains stable by means of the control voltage of TDA The ratio of the chrominance signal to the colour sync signal is at datxsheet contrast 3 dB below maximum and at nominal saturation 6 dB below maximum the same at the output and at the input.
