NOTES:
1. Stresses greater than those listed under ‘Absolute Maximum Ratings’ may cause permanent damage to the device. This is a stress rating for
transient conditions only. Functional operation of the device at these or any other conditions above those indicated in the ‘Operating Range’
section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. Outputs should not be shorted for more than 30 seconds. No more than one output should be shorted at any time.
