74HC165 8-BIT PARALLEL-LOAD SHIFT REGISTERS FEATURES DESCRIPTION • • • • • • • • • • The ’HC165 devices are 8-bit parallel-load shift registers that, when clocked, shift the data toward a serial (QH) output. 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 ’HC165 devices also feature a clock-inhibit (CLK INH) function and a complementary serial (QH) output. 1 Wide Operating Voltage Range of 2 V to 6 V Outputs Can Drive Up To 10 LSTTL Loads Low Power Consumption, 80-μA Max ICC Typical tpd = 13 ns ±4-mA Output Drive at 5 V Low Input Current of 1 μA Max Complementary Outputs Direct Overriding Load (Data) Inputs Gated Clock Inputs Parallel-to-Serial Data Conversion Clocking is accomplished by a low-to-high transition of the clock (CLK) input while SH/LD is held high and CLK INH is held low. The functions of CLK and CLK INH are interchangeable. Since a low CLK and a lowto-high transition of CLK INH also accomplish 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. While SH/LD is low, the parallel inputs to the register are enabled independently of the levels of the CLK, CLK INH, or serial (SER) inputs.
