(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

DESCRIPTION
The SN74LV165A-EP is a parallel-load, 8-bit shift register 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
SN74LV165A-EP features 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 should 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.
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.
