8Bit Addressable Latch
The MC74AC259/74ACT259 is a highspeed 8bit 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 1of8 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 8bit
addressable latch.
