MM74C164
8-Bit Parallel-Out Serial Shift Register
General Description
The MM74C164 shift registers are a monolithic comple-
mentary MOS (CMOS) integrated circuit constructed with
N- and P-channel enhancement transistors. These 8-bit
shift registers have gated serial inputs and clear. Each reg-
ister bit is a D-type master/slave 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 inde-
pendent of the clock and accomplished by a low level at the
clear input. All inputs are protected against electrostatic
effects.
