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.
