IDT54/74FCT139T/AT/CT FAST CMOS DUAL 1-OF-4 DECODER WITH ENABLE MILITARY AND INDUSTRIAL TEMPERATURE RANGE FAST CMOS 1-OF-4 DECODER WITH ENABLE IDT54/74FCT139T/AT/CT FEATURES: DESCRIPTION: - - - - The IDT54/74FCT139T is a dual 1-of-4 decoder built using an advanced dual metal CMOS technology. These devices have two independent decoders, each of which accept two binary weighted inputs (A 0-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. - - - - - Std., A and C speed grades Low input and output leakage 1 A (max.) CMOS power levels True TTL input and output compatibility * VOH = 3.3V (typ.) * VOL = 0.3V (typ.)

Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. No terminal voltage may exceed Vcc by +0.5V unless otherwise noted. FUNCTION TABLE 2.
