Relationship between Vi, Vo1, VV, IV, and Vo1/Vo nom
versus time.
1 VME request: minimum 4 ms
2 tlow min = 40 – 200 ms, typically 80 ms
3 VV level not defined at Vo1 < 2.0 V
4 The V signal drops simultaneously with the output voltage, if
the pull-up resistor R P is connected to Vo1+. The V signal
remains high, if R P is connected to an external source.
