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.

§
The drive strength of the EVA PWM pins and the EVB PWM pins are 
not 
identical.
VCCA should not exceed VDD by 0.3 V.
#The input buffers used in 240x/240xA are 
not 
5-V compatible.
