FAST CMOS OCTAL
BUFFER/LINE DRIVER
IDT54/74FCT240AT/CT
FEATURES:
• 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
– Military: CERDIP, LCC
DESCRIPTION:
The IDT octal buffer/line driver is built using an advanced dual metal
CMOS technology. The FCT240T is designed to be employed as a memory
and address driver, clock driver, and bus-oriented transmitter/ receiver
which provides improved board density.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability. No terminal voltage may exceed
Vcc by +0.5V unless otherwise noted.
2. Inputs and Vcc terminals only.
3. Output and I/O terminals only.
