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) input. The 'LV165A devices feature a clock-inhibit function and a complemented serial output, QH.
Clocking is accomplished by a low-to-high transition of the clock (CLK) input while SH/LD is held high and clock inhibit (CLK INH) is held low. The functions of CLK and CLK INH are interchangeable. Since a low CLK and a low-to-high transition of CLK INH
accomplishes clocking, CLK INH must be changed to the high level only while CLK is high. Parallel loading is inhibited when
SH/LD is held high. The parallel inputs to the register are enabled while SH/LD is held low, independently of the levels of CLK, CLK INH, or SER.
These devices are fully specified for partial-powerdown applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
