ta = -55° to 125° c for all packages
the in74hc165a is identical in pinout to the ls/als165. the device inputs are compatible with standard cmos outputs; with pullup resistors, they are compatible with ls/alsttl 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 input is low, the data is loaded asynchronously in parallel. when the serial shift/parallel load 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.
? outputs directly interface to cmos, nmos, and ttl
? operating voltage range: 2.0 to 6.0 v
? low input current: 1.0 μa
? high noise immunity characteristic of cmos devices
