* These parameters are characterized but not tested.

† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested.

Note:
  1. Response time measured with one comparator input at VDD/2, while the other input transitions from VSS to VDD.
