DESCRIPTION:
The IDT octal buffer/line driver is built using an advanced dual metal
CMOS technology. The FCT2244T is designed to be employed as a
memory and address driver, clock driver, and bus-oriented transmitter/
receiver which provides improved board density.
The FCT2244T has balanced output drive with current limiting resistors.
This offers low ground bounce, minimal undershoot, and controlled output
fall times, reducing the need for external series terminating resistors. The
FCT2244T is a plug-in replacement for the FCT244T.

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. Inputs and Vcc terminals only.
3. Output and I/O terminals only.
