General Description

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 permitting one input to be used as a clock inhibit function.
