1 VCC must not exceed VDD by more than 0.4 V. If it is possible for this to
happen during power-up or power-down (for example, if VCC is greater than
0.4 V while VDD is still 0 V), the following diode protection scheme ensures
protection.

2 VOUT can be shorted to DGND, + 10 V, 10 V, provided that the power
dissipation of the package is not exceeded.
3 Transient currents of up to 100 mA do not cause SCR latch-up.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
