Notes:
1. Permanent device damage may occur if the absolute maximum ratings are exceeded. Functional operation should be
restricted to the conditions as specified in the operational sections of this data sheet. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
2. VDE certifies storage temperature from –40 to 150 °C.
3. Latchup immunity specification is for slew rate applied across GNDI and GNDA or GNDB.
