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: 1.5k

Ω in series with 100pF. Machine model: 200pF, no series

resistance.

4. Specification for packaged product only.
