DESCRIPTION:

The IDT54/74FCT139/A/C are dual 1-of-4 decoders built
using an advanced dual metal CMOS technology. These
devices have two independent decoders, each of which
accept two binary weighted inputs (A0-A1) and provide four
mutually exclusive active LOW outputs (

O0-O

3). Each de-

coder has an active LOW enable (E). When E is HIGH, all
outputs are forced HIGH.
