IDT74FCT540AT/CT FAST CMOS OCTAL BUFFER/LINE DRIVER INDUSTRIAL TEMPERATURE RANGE FAST CMOS OCTAL BUFFER/LINE DRIVER IDT74FCT540AT/CT FEATURES: − − − − − − − − Low input and output leakage ≤1µ A (max.) CMOS power levels True TTL input and output compatibility VOH = 3.3V (typ.) VOL = 0.3V (typ.) Meets or exceeds JEDEC standard 18 specifications A and C speed grades High drive outputs (-15mA IOH, 64mA IOL) Power off disable outputs permit “live insertion” Available in SOIC, SSOP, and QSOP packages DESCRIPTION: The IDT octal buffer/line driver is built using an advanced dual metal CMOS technology. The FCT540T is similar in function to the FCT240T, except that the inputs and outputs are on opposite sides of the package. This pinout arrangement makes these devices especially useful as output ports for microprocessors and as backplane drivers, allowing ease of layout and greater board density.
