Notes: 1. See Figure 31 for timing diagram.
Notes: 2. See Figure 25 for equivalent load.
Notes: 3. This parameter describes the lowest possible VCC level for which the outputs RESET, V2FAIL, and V3FAIL will be correct with respect to
their inputs (VCC, V2MON, V3MON).
Notes: 4. From MR rising edge crossing VIH, to RESET rising edge crossing VOH.
