DESCRIPTION:
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.
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.
The IDT octal buffer/line driver is built using an advanced dual metal
The FCT2244T has balanced output drive with current limiting resistors.
