†
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 V
SS
.
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 information, see the IC Package Thermal Metrics Application Report (literature number SPRA953) and
the Reliability Data for TMS320LF24x and TMS320F281x Devices Application Report (literature number SPRA963).
