3 Description
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-power-
down applications using Ioff. The Ioff circuitry disables
the outputs, preventing damaging current backflow
through the devices when they are powered down.
