Texas Instruments SN74AHCT594/SN74AHCT594-Q1 8-Bit Shift Registers
Texas Instruments SN74AHCT594/SN74AHCT594-Q1 8-Bit Shift Registers contain an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The shift and storage registers provide separate clocks and direct overriding clear (SRCLR, RCLR) inputs. A serial (QH) output is provided for cascading purposes. The Texas Instruments SN74AHCT594-Q1 devices are AEC-Q100 qualified for automotive applications.
