TECHNICAL DATA  
KK74ACT240  
Octal 3-State Inverting Buffer/Line  
Driver/Line Receiver  
High-Speed Silicon-Gate CMOS  
The KK74ACT240 is identical in pinout to the LS/ALS240,  
HC/HCT240. The KK74ACT240 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.

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  
V
OUT)≤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.
