IDT54/74FCT244T/AT/CT FAST CMOS OCTAL BUFFER/LINE DRIVER MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS OCTAL IDT54/74FCT244T/AT/CT BUFFER/LINE DRIVER FEATURES: DESCRIPTION: Std., 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 FCT244T is designed to be employed as a memory CMOS power levels and address driver, clock driver, and bus-oriented transmitter/ receiver True TTL input and output compatibility: which provides improved board density. VOH = 3.3V (typ.) VOL = 0.3V (typ.) High Drive outputs (-15mA IOH, 64mA IOL) Meets or exceeds JEDEC standard 18 specifications Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) Power off disable outputs permitlive insertio Available in the following packages: Industrial: SOIC, SSOP, QSOP, TSSOP Military: CERDIP, LCC FUNCTIONAL BLOCK DIAGRAM OEA OEB OA0 DA0 DB0 OB0 OA1 DA1 DB1 OB1 OA2 DA2 DB2 OB2 OA3 DA3 DB3 OB3 IDT and the IDT logo are registered trademarks of Integrated Device Technology, Inc.
