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.
