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.
- Binary to 1 of 4 Decoders or 1 to 4 Line
Demultiplexer

• 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.
- Standard Outputs. . . . . . . . . . . . . . . 10 LSTTL Loads

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.
