3 Description

The SN74HCT165-Q1 is a parallel- or serial-in, serialout

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-Q1 also features a

clock-inhibit (CLK INH) function and a complementary

serial (Q H) output.
