Electrical Characteristics
All signals are measured with respect to ground GND pin. The voltage levels are valid if other ratings are not violated.
Attention: Limits are subject to change according to test engineering results

Values indicated under “absolute maximum ratings” must not be exceeded.
Values indicated under “operating conditions” can be exceeded if a corresponding explicit “absolute maximum rating” is
given for this parameter, but the related function of the device is not ensured.
6.2
Absolute Maximum Ratings
Stresses above the values listed below may cause permanent damage to the device. Exposure to absolute maximum rating
conditions for given periods may affect device reliability. Maximum ratings are absolute ratings; exceeding anyone of these
values may cause irreversible damage to the device.
