† Clamp current stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress

ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating

conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values are with respect to VSS.

2. Long−term high−temperature storage and/or extended use at maximum temperature conditions may result in a reduction of overall

device life. For additional thermal reliability data for these devices, contact Texas Instruments.
