FAST CMOS OCTAL

BUFFER/LINE DRIVER

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.
