Texas Instruments SN74AC165/SN74AC165-Q1 8-Bit Shift Registers
Texas Instruments SN74AC165/SN74AC165-Q1 8-Bit Parallel Input Shift Registers have a serial data input (SER), standard and inverted serial outputs (QH, /QH), and clock inhibit input (CLK INH). A parallel-in access to each stage is provided by eight individual direct data (A-H) inputs enabled by a low level at the shift/load (SH//LD) input. These devices also feature a complementary serial (/QH) output and a clock-inhibit (CLK INH) function. The Texas Instruments SN74AC165-Q1 devices are AEC-Q100 qualified for automotive applications.
