SN74ACT164-Q1 8-Bit SIPO Shift Registers

Texas Instruments SN74ACT164-Q1 8-Bit Serial-In/Parallel-Out (SIPO) Shift Registers contain an 8-bit shift register with asynchronous clear (CLR) input and AND-gated serial inputs. The gated serial inputs (A and B) permit 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, determining the first flip-flop's state. Provided the minimum set-up time requirements are met, the data at the serial inputs can be changed while CLK is low or high. The clocking occurs on the low-to-high-level transition of CLK. Texas Instruments SN74ACT164-Q1 devices are AEC-Q100 qualified for automotive applications.
