8−Bit Addressable Latch

The MC74AC259/74ACT259 is a high−speed 8−bit addressable

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.
