The 'ALS165 are parallel-load 8-bit serial shift registers that, when clocked, shift the data toward serial (QH and Q\H) outputs. Parallel-in access to each stage is provided by eight individual direct data (A-H) inputs that are enabled by a low level at the shift/load (SH/LD\) input. The 'ALS165 have a clock-inhibit function and complemented serial outputs.

Clocking is accomplished by a low-to-high transition of the clock (CLK) input while SH/LD\ is held high and the clock inhibit (CLK INH) input 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 also 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 low independently of the levels of the CLK, CLK INH, or serial (SER) inputs.

The SN54ALS165 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS165 is characterized for operation from 0°C to 70°C.
