HD74LS259 8-bit Address Latch REJ03D0471–0200 Rev.2.00 Feb.18.2005 This 8-bit addressable latch is designed for general purpose storage applications in digital systems. Specific uses include working registers, serial-holding registers, and active-high decoders or demultiplexers. This is multifunctional device capable of storing single-line data in eight addressable latches, and being a 1-to-8 decoder or demultiplexer with active-high outputs. Four distinct modes of operation are selectable by controlling the clear and enable inputs as enumerated in the function table. In the addressable-latch mode, data at the data-in terminal is written into the addressed latch. The addressed latch will follow the data input with all unaddressed latches remaining in their previous states.
