FAST AND LS TTL DATA
8-BIT ADDRESSABLE LATCH
The SN54/74LS259 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.
