Description

These 8-bit addressable latches are designed for general-purpose storage applications in digital systems. Specific uses include working registers, serial-holding registers, and active-high decoders or demultiplexers. They are multifunctional devices capable of storing single-line data in eight addressable latches and being a 1-of-8 decoder or demultiplexer with active-high outputs.

Four distinct modes of operation are selectable by controlling the clear () and enable (G\) inputs as shown in the function table. In the addressable-latch mode, data at the data-in terminal is written into the addressed latch. The

addressed latch follows the data input with all unaddressed latches remaining in their previous states.
