HITACHI HD74HC165

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. When taken low, data at the
parallel inputs is loaded directly into the register independent of the state of the clock.
