Description

The IDT55FCT139A 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-O3). Each   de- coder has an active LOW enable (E). When E is HIGH, all outputs are forced HIGH.
