IDT54/74FCT139T/AT/CT

FAST CMOS DUAL

1-OF-4 DECODER

WITH ENABLE

Integrated Device Technology, Inc.

FEATURES:

• 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.)

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 de-

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

outputs are forced HIGH.

– 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
