NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or at any other condition above those indicated in the operation section of this specification is not
implied.
2. For operating at elevated temperatures, the device must be derated based on +150
°
C maximum junction temperature.
3. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effect of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying any voltages larger than the rated maxima.
4. Parameters are valid over operating temperature range unless otherwise specified. See ordering code table for applicable temperature
range and operating supply range.
