Notes: 1. See Figure 23 for timing diagram.
Notes: 2.See Figure 18 for equivalent load.
Notes: 3.This parameter describes the lowest possible Vcc / V1 level for which the outputs V2RO, and V3RO will be correct with respect to their
inputs ( V2, V3).
Notes: 4.The above parameters are not 100% tested.
