MM74HCT164

8-Bit Serial-in/Parallel-out Shift Register

The 74HCT logic family is functionally as well as pin-out

compatible with the standard 74LS logic family. All inputs

are protected from damage due to static discharge by inter-

nal diode clamps to V_CCand ground.

General Description

The MM74HCT164 utilizes advanced silicon-gate CMOS

technology. It has the high noise immunity and low con-

sumption of standard CMOS integrated circuits. It also

offers speeds comparable to low power Schottky devices.

MM74HCT devices are intended to interface between TTL

and NMOS components and standard CMOS devices.

These parts are also plug-in replacements for LS-TTL

devices and can be used to reduce power consumption in

existing designs.

This 8-bit shift register has gated serial inputs and CLEAR.

Each register bit is a D-type master/slave flip-flop. Inputs A

& B permit complete control over the incoming data. A

LOW at either or both inputs inhibits entry of new data and

resets the first flip-flop to the low level at the next clock

pulse. A HIGH level on one input enables the other input

which will then determine the state of the first flip-flop. Data

at the serial inputs may be changed while the clock is HIGH

or LOW, but only information meeting the setup and hold

time requirements will be entered. Data is serially shifted in

and out of the 8-bit register during the positive going transi-

tion of the clock pulse. Clear is independent of the clock

and accomplished by a low level at the CLEAR input.

Features

■ Typical propagation delay: 20 ns

■ Low quiescent current: 40 µA maximum (74HCT Series)

■ Low input current: 1 µA maximum

■ Fanout of 10 LS-TTL loads

■ TTL input compatible
