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.
