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.
