MM54C164MM74C164

8-Bit Parallel-Out Serial Shift Register

General Description

The MM54C164MM74C164 shift registers are a monolithic

complementary MOS (CMOS) integrated circuit constructed

with N- and P-channel enhancement transistors These 8-bit

shift registers have gated serial inputs and clear Each regis-

ter bit is a D-type masterslave flip-flop A high-level input

enables the other input which will then determine the state

of the flip-flop

Data is serially shifted in and out of the 8-bit register during

the positive going transition of clock pulse Clear is indepen-

dent of the clock and accomplished by a low level at the

clear input All inputs are protected against electrostatic ef-

fects
