2 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.
