Serial-In, Parallel-Out Shift Register
Description
The HD74AC164/HD74ACT164 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 independent of the
clock.
