IDT54/74FCT139T/AT/CT FAST CMOS DUAL 1-OF-4 DECODER WITH ENABLE Integrated Device Technology, Inc. FEATURES: 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. • • • • • Std., A and C speed grades Low input and output leakage ≤1µA (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 Product available in Radiation Tolerant and Radiation Enhanced versions Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) Available in DIP, SOIC, QSOP, CERPACK and LCC packages FUNCTIONAL BLOCK DIAGRAM Ea A0a A1a PIN CONFIGURATIONS Eb A0b Ea 1 A0a A1a 2 3 O0a 4 O1a O2a 5 O3a GND 7 10 O1b O2b 8 9 O3b A1b 6 P16-1 D16-1 SO16-1 SO16-7 & E16-1 16 VCC 15 Eb 14 A0b 13 A1b O0b 12 11 DIP/SOIC/QSOP/CERPACK TOP VIEW O0b O1b O2b 1 20 19 18 A0b 5 17 A1b 6 16 NC 7 15 O0b 8 14 O1b O3b 2566 drw 01 3 2 A1a 4 O0a NC O1a O2a Eb O3a NC O2a Ea O1a A0a O0a V CC INDEX 2566 drw 02 L20-2 O2b O 3b GND NC O3a 9 10 11 12 13 2566 drw 03 LCC TOP VIEW The IDT logo is a registered trademark of Integrated Device Technology, Inc.
