Notes: 4. Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause SCR
latch-up.
5. The maximum over/under voltage is limited by the input current.
6. Applies to normal operation. Greater differences during power up/down will not cause SCR latch-up.
WARNING: Operation beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
