I have a question about the level VOH in MC13224V. I have a board with a MC13224V powered by a 3.1V voltage. In a series of five boards I have two with output levels of 2.4V and three with roughly 3.1V. Those levels include Serial ports. The behavior of the microprocessor is correct as far as I test. What could this behavoir due to?. I have checked the hi and Lo driver register with no difference in level.
Thanks in advance
