OCTAL 3-STATE INVERTING BUFFER/LINE DRIVER/LINE RECEIVER

Integral Corp. 

IN74ACT240

OCTAL 3-STATE INVERTING BUFFER/LINE

DRIVER/LINE RECEIVER

High-Speed Silicon-Gate CMOS

The IN74ACT240 is identical in pinout to the LS/ALS240,

HC/HCT240. The IN74ACT240 may be used as a level converter

for interfacing TTL or NMOS outputs to High Speed CMOS

inputs.

This octal inverting buffer/line driver/line receiver is designed

to be used with 3-state memory address drivers, clock drivers,

and other bus-oriented systems. The device has inverting

outputs and two active-low output enables.

• TTL/NMOS Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 4.5 to 5.5 V

• Low Input Current: 1.0 µA; 0.1 µA @ 25°C

• Outputs Source/Sink 24 mA
