Overview

HD74HC165 Parallel-load 8-bit Shift Register Description This 8-bit serial shift register shifts data from QA 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.
Holding either of the clock inputs high inhibits clocking, and holding either clock input low with the Shift/Load input high enables the other clock input.
Data transfer occurs on the positive going edge of the clock.
Parallel loading is inhibited as long as the Shift/Load input is high.
