(X = 1,2,3) PROGRAMMING PARAMETERS (See Figure 28)
Notes: The above parameters are not 100% tested.
V1RO, V2RO, V3RO OUTPUT TIMING. (See Figure 25, Figure 26, Figure 27)
Notes: 1.See Figure 26 for timing diagram.
Notes: 2.See Figure 20 for equivalent load.
Notes: 3.This parameter describes the lowest possible V1/Vcc level for which the outputs V1RO, V2RO, and V3RO will be correct with respect to
their inputs (V1/Vcc, V2, V3).
Notes: 4.From MR rising edge crossing V
