M54HC7240/7241/7244 M74HC7240/7241/7244 are high performance CMOS eight-way buffers with strong output drive capability, high noise immunity, symmetric output current, symmetric delays, wide operating voltage range and other features.

The M54HC4538/M74HC4538 is a high performance CMOS bistable multivibrator fabricated in silicon gate C2MOS technology. It has the same high performance as LSTTL combined with true CMOS low power consumption. Each multivibrator features both a negative, A, and a positive, B, edge triggered input, either of which can be used as an inhibit input. Also included is a clear input that when taken low resets the one shot. The monostable multivibrators are retriggerable. That is, they may be triggered repeatedly while their outputs are generating a pulse and the pulse will be extended. Pulse width stability over a wide range of temperature and supply is achieved using linear CMOS techniques. The output pulse equation is simply PW = 0.7 (R)(C) where R is the output resistance and C is the output capacitance.

TDA9105A is a video signal processing chip produced by Texas Instruments. The chip integrates horizontal and vertical synchronization signal generation, line field synchronization signal generation, line field scanning drive circuit, horizontal and vertical synchronization signal output, line field video signal output, line field video signal gain control circuit, line field video signal automatic tracking circuit, line field video signal edge compensation circuit, line field video signal geometric correction circuit, line field video signal static focus circuit, line field video signal dynamic focus circuit etc.

The L6506/Dis a linear integrated circuit designed to sense and control the current in stepping motors and similar devices. When used in conjunction with the L293, L298, L7150, L6114/L6115, the chip set forms a constant current drive for an inductive load and performs all the interface function from the control logic thru the power stage. Two or more devices may be synchronized using the sync pin. In this mode of operation, the oscillator in the master chip sets the operating frequency in all chips.

The TODV 640 ---> 1240 are four TOD series converters. They use high performance passivated glass technology with very high commutation levels and high surge current capability, which are suitable for power control on inductive loads (motors, transformers).

HCC/HCF4093B Quad 2-input NAND Schmitt Triggers

The GS3T5-5.2 is a 3.12W DC-DC converter designed by SGS-THOMSON Microelectronics to provide an isolated 5.2V/600mA power source. The module operates from a 5V input source and features continuous short-circuit protection.

M54/74HCT86 is a high-performance CMOS quad exclusive or gate with input buffers and output buffers. The input has electrostatic protection circuits and overvoltage protection circuits. The output has a 10 LSTTL load capacity.

STV8225 is a sound demodulator chip produced by STMicroelectronics of Italy

M54HC157/158 M74HC157/158 are high speed CMOS QUAD 2-CHANNEL MULTI- PLEXER’s fabricated with silicon gate C2MOS tech- nology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. These devices consist of four 2-input digital multi- plexers with common select and strobe inputs. The HC158 is an inverting multiplexer while the HC157 is a non-inverting multiplexer. When the STROBE input is held High, selection of data is inhibited and all the outputs become Low in the M74HC157 and High in the M74HC158. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. All inputs are equipped with protection circuits against static dis- charge and transient.

TS68HC901 HCMOS multi-function peripheral, which has 8 input/output pins, 16 source interrupt controllers, four timers with individually programmable prescaling, a single channel USART.

The M54/74HC690/691/692/693 are high-speed CMOS counters/registers fabricated in silicon gate C2MOS technology. They offer the high-speed performance of LSTTL combined with the low power consumption of CMOS. The internal circuit consists of three stages, including a buffer output, which provides high noise immunity and stable output. These devices integrate a synchronous counter, a four-bit D-type register, and quadruple two-line to one-line multiplexers with three-state outputs in a single 20-pin package. The counter can be programmed using the data inputs and features enable P and enable T inputs for easy expansion. The device can function as either a counter or a parallel register output.
