Notes: 25. Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause
SCR latch-up.
26. The maximum over or under voltage is limited by the input current.
Warning:
Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
