1. Operating characteristics are over Standard Operating Conditions unless otherwise specified.
2. The disturbance on V CC during supply changeover should be kept below the hysteresis voltage to prevent any chatter. The source resistance
on the V CC supply should be kept to less than 0.3 W to ensure precise switching.
