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

1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second.
4. This parameter is guaranteed but not tested.

1. For conditions shown as Max. or Min., 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 the ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC DHNT + ICCD (fCP/2 + foNO)
ICC = Quiescent Current
∆ICC = 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 Output Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
fo = Output Frequency
NO = Number of Outputs at fo
All currents are in milliamps and all frequencies are in megahertz.
