8-Bit Shift Register (S-IN, P-OUT)

The TC74ACT164 is an advanced high speed CMOS 8-BIT SERIAL-IN PARALLEL-OUT SHIFT REGISTER fabricated with silicon gate and double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels.
It consists of a serial-in, parallel-out 8-bit shift register with a CLOCK input and an overriding CLEAR input.
Two serial data inputs (A, B) are provided so that one may be used as a data enable.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
