DESCRIPTION

The M54/74HCT164 is a high speed CMOS 8 BIT

SIPO SHIFT REGISTER fabricated in silicon gate

C²MOS technology. It has the same highspeed per-

formance of LSTTL combined with true CMOS low

power consumption.

PIN CONNECTIONS (top view)

The HCT164 is an 8 bit shift register with serial data

entry and an output from each of the eight stages.

Data is entered serially through one of two inputs (A

or B), either of these inputs can beused asan active

high enable for data entry through the other input.

An unused input must be high, or both inputs con-

nected together. Each low-to-high transition on the

clock input shifts data one place to the right and

entersintoQA, thelogic NAND of the twodata inputs

(A • B), the data that existed before the rising clock

edge. A low level on the clear input overrides all

other inputs and clearsthe register asynchronously,

forcing all Q outputs low.

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.

This integrated circuit has input and output charac-

teristics that are fully compatible with 54/74 LSTTL

logic families. M54/74HCT devices are designed to

directly interface HSC²MOS systems with TTL and

NMOS components. They are also plug in replace-

ments for LSTTL devices giving a reduction of

power consumption.
