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. Serial–to–Parallel Conversion Eight Bits of Storage with Output of Each Bit Available Random (Addressable) Data Entry Active High Demultiplexing or Decoding Capability Easily Expandable Common Clear
