DM54LS165 Product details

Description

This device is an 8-bit serial shift register which shifts data in the direction of QA toward QH when clocked Parallel-in access is made available by eight individual direct data inputs which 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 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 cl
