Features  
Description  
• Multifunction Capability  
The ’HC139 and ’HCT139 devices contain two independent  
binary to one of four decoders each with a single active low  
enable input (1E or 2E). Data on the select inputs (1A0 and  
1A1 or 2A0 and 2A1) cause one of the four normally high  
outputs to go low.

• Active Low Mutually Exclusive Outputs  
• Fanout (Over Temperature Range)  
If the enable input is high all four outputs remain high. For  
demultiplexer operation the enable input is the data input.  
The enable input also functions as a chip select when these  
devices are cascaded. This device is functionally the same  
as the CD4556B and is pin compatible with it.

The outputs of these devices can drive 10 low power  
Schottky TTL equivalent loads. The HCT logic family is  
functionally as well as pin equivalent to the LS logic family.
