These 8-bit addressable latches are designed for  
general-purpose storage applications in digital  
systems. Specific uses include working registers,  
serial-holding registers, and active-high decoders  
or demultiplexers. They are multifunctional  
devices capable of storing single-line data in eight  
addressable latches and being a 1-of-8 decoder  
or demultiplexer with active-high outputs.
