† 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 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).

§ The drive strengths of the EVA PWM pins and the EVB PWM pins are not identical.

¶ VCCA should not differ from VDD by more than 0.3 V.

# The input buffers used in 240x/240xA are not 5-V compatible.
