3 Description
The SN74HCS259 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.
