IDT54/74FCT139/A/C FAST CMOS DUAL 1-0F-4 DECODER WITH ENABLE ® MILITARY AND COMMERCIAL TEMPERATURE RANGES FAST CMOS DUAL 1-OF-4 DECODER WITH ENABLE DESCRIPTION: IDT54/74FCT139 IDT54/74FCT139A IDT54/74FCT139C Integrated Device Technology, Inc. FEATURES: IDT54/74FCT139 equivalent to FAST™ speed IDT54/74FCT139A 35% faster than FAST IDT54/74FCT139C 45% faster than FAST Equivalent to FAST output drive over full temperature and voltage supply extremes IOL = 48mA (commercial) and 32mA (military) CMOS power levels (1mW typ. static) TTL input and output level compatible CMOS output level compatible Substantially lower input current levels than FAST (5µA max.) JEDEC standard pinout for DIP and LCC Product available in Radiation Tolerant and Radiation Enhanced versions Military product compliant to MIL-STD-883, Class B The IDT54/74FCT139/A/C 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.
