DESCRIPTION:
The IDT octal buffer/line drivers are built using an advanced
dual metal CMOS technology. The IDT54/74FCT240/A/C,
IDT54/74FCT241/A/C and IDT54/74FCT244/A/C are designed
to be employed as memory and address drivers, clock drivers
and bus-oriented transmitter/receivers which provide improved
board density.
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
arrangement makes these devices especially useful as output
ports for microprocessors and as backplane drivers, allowing
ease of layout and greater board density.

NOTES:
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.
