Summary: Each device contains an 8-bit SIPO shift register and an 8-bit D-type storage register.

SN74AHCT165-SN74AHCT165-q1 Texas Instruments

The SN74AHCT165/SN74AHCT165-q1 serial input/parallel output (SIPO) shift register contains an 8-bit serial input, parallel output shift register. Each register provides an 8-bit D-type storage register. These storage registers have parallel tri-state outputs. Separate clocks are provided for both storage registers and shift registers. The shift register has a serial (SER) input, a direct override clear (SRCLR) input, and a serial output for cascading. When the Output Enable (OE) input is high, all outputs (except QH) are in a high-impedance state. The Texas Instruments SN74AHCT165-Q1 device is qualified for AEC-Q100 automotive applications.
