description/ordering information
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.
