Enhanced product eight-bit parallel-load shift registers

The SN74LV165B-EP device is a parallel-load, 8-bit shift registers designed for 2 V to 5.5 V V CC operation.

When the device is clocked, data is shifted toward the serial output Q H. 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 SN74LV165B-EP devices features a clock-inhibit function and a complemented serial output, Q H.

This device is fully specified for partial-power-down applications using I off. The I off circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
