Note 1: Operating characteristics are over Standard Operating Conditions unless otherwise specified.

Note 2: The disturbance on VCC during supply changeover should be kept below the hysteresis voltage to prevent any chatter. The

source resistance on the VCC supply should be kept to less than 0.3 ohms to ensure precise switching.
