The SN74HCT165 is a parallel- or serial-in, serial-out 8-bit shift register. Parallel-in access to each stage is provided by eight individual direct data (A-H) inputs that are enabled by a low level at the shift/load (SH/LD) input. The SN74HCT165 also features a clock-inhibit (CLK INH) function and a complementary serial (Q H) output.
