Note 1: Operating supply range is guaranteed by VL line regulation test for the range of 5.5V to 28V. Between 4.5V and 5.5V, the V_L
regulator might be in dropout; however, the part continues to operate properly.
Note 2: Guaranteed by design and not production tested.
Note 3: Specifications to -40°C are guaranteed by design and not production tested.
