IDT74FCT2244AT/CT FAST CMOS OCTAL BUFFER/LINE DRIVER INDUSTRIAL TEMPERATURE RANGE FAST CMOS OCTAL IDT74FCT2244AT/CT BUFFER/LINE DRIVER FEATURES: DESCRIPTION: A and C grades The IDT octal buffer/line driver is built using an advanced dual metal Low input and output leakage 1A (max.) CMOS technology. The FCT2244T is designed to be employed as a CMOS power levels memory and address driver, clock driver, and bus-oriented transmitter/ True TTL input and output compatibility: receiver which provides improved board density. VOH = 3.3V (typ.) The FCT2244T has balanced output drive with current limiting resistors. VOL = 0.3V (typ.) This offers low ground bounce, minimal undershoot, and controlled output Meets or exceeds JEDEC standard 18 specifications fall times, reducing the need for external series terminating resistors. The Resistor outputs (-15mA IOH, 12mA IOL) FCT2244T is a plug-in replacement for the FCT244T.
