MM54HCT164MM74HCT164
8-Bit Serial-inParallel-out Shift Register
General Description
The MM54HCT164MM74HCT164 utilizes advanced sili-
con-gate CMOS technology It has the high noise immunity
and low consumption of standard CMOS integrated circuits
It also offers speeds comparable to low power Schottky de-
vices
This 8-bit shift register has gated serial inputs and CLEAR
Each register bit is a D-type masterslave 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 re-
quirements will be entered Data is serially shifted in and out
of the 8-bit register during the positive going transition of the
clock pulse Clear is independent of the clock and accom-
plished by a low level at the CLEAR input
The 54HCT74HCT logic family is functionally as well as
pin-out compatible with the standard 54LS74LS logic fami-
ly All inputs are protected from damage due to static dis-
charge by internal diode clamps to VCC and ground
MM54HCTMM74HCT devices are intended to interface be-
tween 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
