HD74AC165 Parallel-Load 8-bit Shift Register

This 8-bit serial shift register shifts data from Q A to QH when clocked, Parallel inputs to each stage are enabled by a low level at the Shift/Load Input. Also included is a gated clock input and a complementary output from the eighth bit. Clocking is accomplished through a 2-input NOR gate permitt.
