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. Note 1: These voltage and current ratings are physically independent; each required condition must be enforced by the user (see Section 5.1.2 “Input Voltage Limits” and Section 5.1.3 “Input Current Limits” ). 2: The Absolute Maximum Junction Temperature is not intended for continuous use. 1.2Voltage and Temperature Ranges The various voltage and temperature ranges are listed in Table 1-1.
