SN74LS259
8-Bit Addressable Latch
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.

... FUNCTIONAL DESCRIPTION The SN74LS259 has four modes of operation as shown in the mode selection table. In the addressable latch mode, data on the Data line (D) is written into the addressed latch.The addressed latch will follow the data input with all non-addressed latches remaining in their previous states. In the memory mode, all latches remain in their previous state and are unaffected by the Data or Address inputs ...
