(1) Unless otherwise noted, the list of absolute maximum ratings are specified over operating temperature ranges. 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
is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage values are
with respect to V
.

(2) Continuous clamp current per pin is ±2 mA
(3) 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 TMS320LF24xx and TMS320F28xx Devices Application Report (literature number SPRA963).
