2 / 8 page MC74AC240, MC74ACT240 http://onsemi.com 2 MAXIMUM RATINGS Symbol Parameter Value Unit VCC DC Supply Voltage (Referenced to GND) −0.5 to +7.0 V VIN DC Input Voltage (Referenced to GND) −0.5 to VCC +0.5 V VOUT DC Output Voltage (Referenced to GND) −0.5 to VCC +0.5 V IIN DC Input Current, per Pin ±20 mA IOUT DC Output Sink/Source Current, per Pin ±50 mA ICC DC VCC or GND Current per Output Pin ±50 mA Tstg Storage Temperature −65 to +150 °C 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.
