8−Bit Addressable Latch
latch designed for general purpose storage applications in digital
systems. It is a multifunctional device capable of storing single line
data in eight addressable latches, and also a 1−of−8 decoder and
demultiplexer with active HIGH outputs. The device also incorporates
an active LOW Common Clear for resetting all latches, as well as an
active LOW Enable. It is functionally identical to the ALS259 8−bit
addressable latch.
