MC74HC240AF

MC74HC240A Octal 3−State Inverting Buffer/Line Driver/Line Receiver High−Performance Silicon−Gate CMOS http://onsemi.com The MC74HC240A is identical in pinout to the LS240. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This octal noninverting buffer/line driver/line receiver is designed to be used with 3−state memory address drivers, clock drivers, and other sub−oriented systems. The device has inverting outputs and two active−low output enables. The HC240A is similar in function to the HC244A.

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 v (Vin or Vout) v 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. _C 260 Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. †Derating — Plastic DIP: – 10 mW/_C from 65_ to 125_C SOIC Package: – 7 mW/_C from 65_ to 125_C TSSOP Package: − 6.1 mW/_C from 65_ to 125_C For high frequency or heavy load considerations, see Chapter 2 of the ON Semiconductor High−Speed CMOS Data Book (DL129/D).
