MM74HCT164
8-Bit Serial-in/Parallel-out Shift Register
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.
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.
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
CC
and ground.
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.
