Note 1: Operating characteristics are over Standard Operating Conditions unless otherwise specified.
Note 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 ohms to ensure precise switching.
