−
The IDT octal buffer/line driver is built using an advanced dual metal
CMOS technology. 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.

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
Std., A, and C speed grades
Resistor outputs -15mA IOH, 12mA IOL
Reduced system switching noise
Available in SOIC, SSOP, QSOP, and TSSOP packages
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.
