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

FEATURES:

? Std., A and C speed grades

? Low input and output leakage ≤1μA (max.)

? CMOS power levels

? True TTL input and output compatibility
