8-Bit Addressable Latches  
General Description  
Features  
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 mul-  
tifunctional devices capable of storing single-line data in  
eight addressable latches, and being a 1-of-8 decoder or  
demultiplexer with active-high outputs.  
8-Bit parallel-out storage register performs serial-to-par-  
allel conversion with storage  
Asynchronous parallel clear  
Active high decoder  
Enable/disable input simplifies expansion  
Direct replacement for Fairchild DM9334  
Expandable for N-bit applications  
Four distinct functional modes  
Typical propagation delay times:  
Enable-to-output 18 ns  
Four distinct modes of operation are selectable by control-  
ling the clear and enable inputs as enumerated in the func-  
tion 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 unad-  
dressed latches remaining in their previous states. In the  
memory mode, all latches remain in their previous states  
and are unaffected by the data or address inputs. To elimi-  
nate the possibility of entering erroneous data in the  
latches, the enable should be held HIGH (inactive) while  
the address lines are changing. In the 1-of-8 decoding or  
demultiplexing mode, the addressed output will follow the  
level of the D input with all other outputs LOW. In the clear  
mode, all outputs are LOW and unaffected by the address  
and data inputs.
