1. Operating characteristics are over Standard Operating Conditions unless otherwise specified.
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 W to ensure precise switching.
