description  
This 3-line to 8-line decoder/demultiplexer with latches on three address inputs is designed for 1.65-V to 3.6-V  
operation.  
V
CC  
The SN74LVC137A is designed for high-performance memory-decoding or data-routing applications requiring  
very short propagation delay times. In high-performance memory systems, this decoder can be used to  
minimize the effects of system decoding. When employed with high-speed memories utilizing a fast enable  
circuit, thedelaytimesofthisdecoderandtheenabletimeofthememoryareusuallylessthanthetypicalaccess  
time of the memory. This means that the effective system delay introduced by the decoder is negligible.  
When the latch-enable (G2A) input is low, the SN74LVC137A acts as a decoder/demultiplexer. When G2A  
transitions from low to high, the address present at the inputs (A, B, and C) is stored in the latches. Further  
address changes are ignored, provided G2A remains high. The output-enable (G1 and G2B) inputs control the  
outputs independently of the select or latch-enable inputs. All of the outputs are forced high if G1 is low or G2B  
is high.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators  
in a mixed 3.3-V/5-V system environment.  
The SN74LVC137A is characterized for operation from –40°C to 85°C.
