1 / 5 page Integrated Device Technology, Inc. DESCRIPTION: The IDT54/74FCT139T/AT/CT 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.
