HD74LS165A
Parallel-Load 8-bit Shift Register
REJ03D0449–0300 Rev.3.00
Jul.15.2005
The LS165A are 8-bit serial shift registers that shift the data in the direction of QA toward QH when clocked. Parallel-in access to each stage is made available by eight individual direct data inputs that are enabled by a low level at the shift / load input. These registers also feature gated clock inputs and complementary outputs from the eighth bit. All inputs are diode-clamped to minimize transmission-line effects, thereby simplifying system design.
Clocking is accomplished through a 2-input positive-NOR gate, permitting one input to be used as a clock-inhibit function.
