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

The TC74VHC164 is an advanced high speed CMOS 8-BIT

SERIAL-IN PARALLEL-OUT SHIFT REGISTER fabricated with

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

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.

An input protection circuit ensures that 0 to 5.5 V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.

Features

• Power down protection is provided on all inputs.

• Pin and function compatible with 74ALS164
