IDT54/74FCT139T/AT/CT
DESCRIPTION:
FEATURES:
TheIDT54/74FCT139Tisadual1-of-4decoderbuiltusinganadvanced
dual metal CMOS technology. These devices have two independent
decoders, each of which accept two binary weighted inputs (A0-A1) and
provide fourmutuallyexclusive active lowoutputs (O0-O3).Eachdecoder
has anactive lowenable (E). WhenE is high, alloutputs are forcedhigh.
• Std., A, and C 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
• Military product compliant to MIL-STD-883, Class B and DESC
listed (dual marked)
• Power off disable outputs permit "live insertion"
• Available in the following packages:
– Industrial: SOIC, QSOP
– Military: CERDIP, LCC

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability. No terminal voltage may exceed
Vcc by =0.5V unless otherwise noted.

1. For conditions shown as Min. or Max., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input; (VIN = 3.4V). All other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. Values for these conditions are examples of ΔICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ΔICC DHNT + ICCD (fONO)
ICC = Quiescent Current
ΔICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current caused by an Input Transition Pair (HLH or LHL)
fO = Output Frequency
NO = Number of Outputs at fO
All currents are in milliamps and all frequencies are in megahertz.
