description  
GND  
The SN54ALS137A, SN74ALS137A, and  
SN74AS137 are 3-line to 8-line decoders/  
demultiplexers with latches on the three address  
inputs. When the latch-enable (LE) input is low,  
the devices act as decoders/demultiplexers.  
When LE goes from low to high, the address  
present at the select (A, B, and C) inputs is stored  
in the latches. Further address changes are  
ignored as long as LE remains high. The  
output-enable controls (G1 and G2) control the  
outputs independently of the select or  
latch-enable inputs. All of the outputs are forced  
high if G1 is low or G2 is high. These devices are  
ideally suited for implementing glitch-free  
decoders in strobed (stored-address) applications  
in bus-oriented systems.
