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. Longterm hightemperature 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.

§
The drive strength 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.
