WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation

is not guaranteed at these extremes.

Notes:

1. Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause

SCR latch-up.

2. The maximum over/under voltage is limited by the input current.
