3 Description

The SN74HC165B-EP device is a parallel-load, 8-bit

shift registers designed for 2 V to 6 V VCC operation.

When the device is clocked, data is shifted toward the

serial output QH. Parallel-in access to each stage is

provided by eight individual direct data inputs that are

enabled by a low level at the shift/load (SH/ LD) input.

The SN74HC165B-EP devices features a clock-inhibit

function and a complemented serial output, Q H.
