The ’LV165A devices are parallel-load, 8-bit shift registers designed for 2-V to 5.5-V VCC operation.
When the devices are 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 is held low, independently of the levels of CLK, CLK INH, or SER.
These devices are 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.
