Notes:
1. This condition is for AC function test only, not for AC parameter test.
2. To maintain a valid level, the transitioning edge of the input must :
a) Sustain a constant slew rate from the current AC level through the target AC level, V
IL(AC)
or V
IH(AC)
b) Reach at least the target AC level
c) After the AC target level is reached, continue to maintain at least the target DC level, V
