MC54F164 8-Bit Serial-In Parallel-Out Shift Register

8-BIT SERIAL-IN, PARALLEL-OUT SHIFT REGISTER The MC54/74F164 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. • Ty.
