This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTE: 1. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. Electrical Specifications Operating Conditions: VCC = 5V, TA = 0°C to 70°C, Unless Otherwise Noted. Typical specifications are at TA = 25°C.
