Notes: 1. See Figure 31 for timing diagram.
Notes: 2. See Figure 25 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_IH, to V1RO rising edge crossing V_OH.
Notes: 5. The above parameters are not 100% tested.
