The MC74HC165AMNTWG is identical in pinout to the LS165. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.This device is an 8-bit shift register with complementary outputs from the last stage. Data may be loaded into the register either in parallel or in serial form. When the Serial Shift/Parallel Load(bar) input is low, the data is loaded asynchronously in parallel. When the Serial Shift/Parallel Load(bar) input is high, the data is loaded serially on the rising edge of either Clock or Clock Inhibit (see the Function Table).The 2-input NOR clock may be used either by combining two independent clock sources or by designating one of the clock inputs to act as a clock inhibit.
