Description
The CD54AC139/3A and CD54ACT139/3A are dual 2-to-4-
line decoders/demultiplexers that utilize the Harris Advanced
CMOS Logic technology. These devices contain two inde-
pendent binary to 1-of-4 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.
The CD54AC139/3A and CD54ACT139/3A are supplied in
16 lead dual-in-line ceramic packages (F suffix).
