74ACT164
Serial-In Parallel-Out Shift Register
General Description
The 74ACT164 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
