avoid a default of the applications and the products or of the application or

use by customer’s third party customer(s). Nexperia does not accept any

liability in this respect.

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.

Terms and conditions of commercial sale — Nexperia products are

sold subject to the general terms and conditions of commercial sale, as

published at http://www.nexperia.com/profile/terms, unless otherwise agreed

in a valid written individual agreement. In case an individual agreement is
