FAST CMOS OCTAL BUFFER/LINE DRIVER
IDT54/74FCT244T/AT/CT
FEATURES:
• Std.
, A, and C grades • Low input and output leakage ≤1µA (max.
) • CMOS power levels • True TTL input and output compatibility:
– 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 permit "live insertion" • Available in the following packages: – Industrial: SOIC, SSOP, QSOP, TSSOP – Military: CERDIP, LCC
DESCRIPTION:
The IDT octal buffer/line driver is built using an advanced dual metal CMOS technology.
The FCT244T is designed to be employed as a memory and address driver, clock driver, and bus-oriented transmitter/ receiver which provides improved board density.
