DS21421E-page 3 TC4423/TC4424/TC4425 1.0 ELECTRICAL CHARACTERISTICS Absolute Maximum Ratings † Supply Voltage ................................................................+22V Input Voltage, IN A or IN B ................................................ (VDD + 0.3V) to (GND – 5V) Package Power Dissipation (TA 70°C) DFN ......................................................................... Note 2 PDIP .......................................................................730 mW SOIC.......................................................................470 mW † Notice: Stresses above those listed under "Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended periods may affect device reliability. DC CHARACTERISTICS Electrical Specifications: Unless otherwise indicated, TA = +25°C, with 4.5V VDD18V.
