The IDT octal buffer/line drivers are built using an advanced dual metal
CMOS technology. The FCT541 is designed to be employed as a memory
and address driver, clock driver and bus-oriented transmitter/receiver
which provides improved board density. The FCT541 is similar in function
to the FCT244, except that the inputs and outputs 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.

FUNCTION TABLE(1)
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.
2. Input and Vcc terminals only.
3. Output and I/O terminals only.

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 ∆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 = Output Frequency
Ni = Number of Outputs at fi
