Hi Kenneth,
It is important to measure the overshoot/undershoot with respect to the proper pin and at the proper locations. Ideally a differential probe should measure the output with respect to pin 1 and pin 8 for overshoot, and the output with respect to pin 4 for undershoot. If this is not available, the math function within the scope can also work if the probe grounds are connected at the same location.
I suspect VCC/VM are both rising during the overshoot time. If VCC rises above 7V, this should be addressed.
Please ask for scope captures showing the overshoot and undershoot.
