Hitachi HD74HC166 Parallel-load 8-bit shift register Datasheet

HD74HC166
Parallel-load 8-bit Shift Register
Description
This device is an 8-bit shift register with an output from the last stage. Data may be loaded into the register
either in parallel or in serial form. When the Shift/Load input is low, the data is loaded asynchronously in
parallel. When the Shift/Load input is high, the data is loaded serially on the rising edge of either clock
inhibit or Clock. Clear is asynchronous and active-low.
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.
