DS21987A-page 3 TC4451/TC4452 1.0 ELECTRICAL CHARACTERISTICS Absolute Maximum Ratings † Supply Voltage .....................................................+20V Input Voltage .................... (VDD + 0.3V) to (GND – 5V) Input Current (VIN > VDD)................................... 50 mA † Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. DC CHARACTERISTICS Electrical Specifications: Unless otherwise noted, TA = +25°C with 4.5V ≤ VDD ≤ 18V.
