Supplied as a 16 pin DIL package IC,

The 74LS165A is an 8-bit serial shift register that shifts the data in the direction of QA toward QH when clocked.

Parallel-in access to each stage is made available by eight individual, direct data inputs, that are enabled by a low level at the shift/load (SH/LD) input.

These registers also feature gated clock (CLK) inputs and complementary outputs from the eighth bit.

All inputs are diode-clamped to minimize transmission-line effects, thereby simplifying system design.

Clocking is accomplished through a two-input positive-NOR gate, permitting one input to be used as a clock-inhibit function.

Holding either of the clock inputs high inhibits clocking, and holding either clock input low with SH/LD high enables the other clock input.

Clock inhibit (CLK INH) should be changed to the high level only while CLK is high.

Parallel loading is inhibited as long as SH/LD is high.

Data at the parallel inputs are loaded directly into the register while SH/LD is low, independently of the levels of CLK, CLK INH, or serial (SER) inputs.
