8-Bit Parallel-Out Serial Shift Register, SN74HC164N, Texas Instruments

This 8-bit shift register features AND-gated serial input and an asynchronous clear (CLR) input. The gated serial (A and B) input permits complete control over incoming data; a low at either input inhibits entry of the new data and resets the first flip-flop to the low level at the next clock (CLK) pulse. A high-level input enables the other input, which then determines the state of the first flip-flop. Data at the serial input can be changed while CLK is high or low, provided the minimum set-up time requirement is met. Clocking occurs on the low-to-high-level transition of CLK.
