FEATURES:

DESCRIPTION:

• 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

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 de-

coder has an active LOW enable (E). When E is HIGH, all

outputs are forced HIGH.

• 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
