General 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 mul
tifunctional devices capable of storing single-line data in eight addressable latches, and being a 1-of-8 decoder or demultiplexer with active-high outputs.
