3 Description

The SN74LV165A device is a parallel-load, 8-bit shift

registers designed for 2 V to 5.5 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 ’LV165A devices feature a clock-inhibit function

and a complemented serial output, Q H.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables

the outputs, preventing damaging current backflow

through the devices when they are powered down.
