3 Description

The SN74HCS259-Q1 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.
