IDT54/74FCT139T/AT/CT FAST CMOS 1-OF-4 DECODER WITH ENABLE MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS 1-OF-4 DECODER WITH ENABLE DESCRIPTION: FEATURES: * * * * * * * * * IDT54/74FCT139T/AT/CT 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 (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. Std., A, and C grades Low input and output leakage 1A (max.) CMOS power levels True TTL input and output compatibility: - VOH = 3.3V (typ.) - VOL = 0.3V (typ.) High Drive outputs (-15mA IOH, 48mA IOL) Meets or exceeds JEDEC standard 18 specifications Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) Power off disable outputs permit "live insertion" Available in the following packages: - Industrial: SOIC, QSOP - Military: CERDIP, LCC FUNCTIONAL BLOCK DIAGRAM Ea O 0a A 0a O 1a O 2a Eb A 1a O 3a O 0b The IDT logo is a registered trademark of Integrated Device Technology, Inc.
