Notes:
1. Exceeding the “Absolute Maximum Ratings” may damage the devices.
2. The devices are not guaranteed to function outside the specified Operating Conditions.
3. Devices are ESD sensitive. Handling precautions recommended. Human body model: 1.5kΩ in series with 100pF. Machine model: 200pF, no series
resistance.
4. Specification for packaged product only.
5. Not 100% tested. Parameters are guaranteed by design.
