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, QH.

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.
