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

The TC74VHC165 is an advanced high speed CMOS 8-BIT

PARALLEL/SERIAL-IN, SERIAL-OUT SHIFT REGISTER

It achieves the high speed operation similar to equivalent Bipolar

Schottky TTL while maintaining the CMOS low power dissipation.

It consists of parallel-in or serial-in, serial-out 8-bit shift register

with a gated clock input. When the SHIFT/ LOAD input is held

high, the serial data input is enabled and the eight frip-frops

perform serial shifting with each clock pulse.

When the SHIFT/ LOAD input is held low, the parallel data is

loaded synchronously into the register at positive going transition of

the clock pulse.

The CK-INH input should be shifted high only when the CK input

is held high.

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 V to 3 V systems and on 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 74ALS165
