SN54/74LS259  
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.
