CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. 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.
NOTES:
1. Input voltages may exceed the supply voltages provided the input current is limited to ±100µA.
2. TEST pin is connected to internally generated digital ground through a 500Ω resistor (see text for TEST pin description).
3. θJA is measured with the component mounted on an evaluation PC board in free air.
Electrical Specifications (Notes 5, 6, 7) TA = 25oC. Device is Tested in the Circuit Shown in Figure 2.
