74F164A
Serial-In, Parallel-Out Shift Register
General Description
The 74F164A is a high-speed 8-bit serial-in/parallel-out
shift register. Serial data is entered through a 2-input AND
gate synchronous with the LOW-to-HIGH transition of the
clock. The device features an asynchronous Master Reset
which clears the register, setting all outputs LOW indepen-
dent of the clock. The 74F164A is a faster version of the
74F164.
Features
