Description
The Harris CD74HC139, CD74HCT139 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.
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 74HCT logic family is
functionally as well as pin equivalent to the 74LS logic family.
