TECHNICAL DATA
Octal 3-State Inverting Buffer/Line
Driver/Line Receiver
High-Speed Silicon-Gate CMOS
IN74AC240
The IN74AC240 is identical in pinout to the LS/ALS240,
HC/HCT240. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALSTTL
outputs.
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.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA; 0.1 µA @ 25°C
• High Noise Immunity Characteristic of CMOS Devices
• Outputs Source/Sink 24 mA

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
