Operating Conditions Thermal Information oC (SOIC - Lead Tips Only) CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operationo ft h e 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 an evaluation PC board in free air. Absolute Maximum Voltage RatingsTA = 25oC Absolute Maximum Current Ratings The following chart gives the range of voltages which can be applied to the terminals listed horizontally with respect to the terminals listed vertically. For example, the voltage range of the horizontal Terminal 4 with respect to Terminal 2 is -1V to +5V. TERM N O . 12345678 TERM NO.
