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. DA0 OB0 DA1 OB1 DA2 OB2 DA3 OB3 OEB OA0 DB0 OA1 DB1 OA2 DB2 OA3 DB3 OEA
