I ABSOLUTE MAXIMUM RATINGS
(1)
Preventive Caution: Exceeding the listed absolute maximum ratings below may affect the device negatively and may cause permanent damage. Therefore operating ratings are
conditions under which operation of the device is intended to be functional. All values are referenced to GND and to a free ambient operating temperature of TA=25 ± 5 °C
unless otherwise specified.
