DM54LS165 - 8-Bit Parallel In/Serial Output Shift Registers

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 compl
