• IDT54/74FCT240A/241A/244A/540A/541A 25% faster
than FAST
DESCRIPTION:
TM
TheIDToctalbuffer/linedriversarebuiltusinganadvanced
dual metal CMOS technology. The IDT54/74FCT240/A/C,
IDT54/74FCT241/A/CandIDT54/74FCT244/A/Caredesigned
to be employed as memory and address drivers, clock drivers
andbus-orientedtransmitter/receiverswhichprovideimproved
board density.
• IDT54/74FCT240C/241C/244C/540C/541C up to 55%
faster than FAST
• IOL = 64mA (commercial) and 48mA (military)
• CMOS power levels (1mW typ. static)
• Product available in Radiation Tolerant and Radiation
Enhanced versions
• Military product compliant to MIL-STD-883, Class B
• Meets or exceeds JEDEC Standard 18 specifications
The IDT54/74FCT540/A/C and IDT54/74FCT541/A/C are
similar in function to the IDT54/74FCT240/A/C and IDT54/
74FCT244/A/C, respectively, except that the inputs and out-
puts are on opposite sides of the package. This pinout
arrangementmakesthesedevicesespeciallyusefulasoutput
ports for microprocessors and as backplane drivers, allowing
ease of layout and greater board density.

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 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 + fiNi)
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 Input Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
fi = Input Frequency
Ni = Number of Inputs at fi
All currents are in milliamps and all frequencies are in megahertz.
