Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5kΩ in series with 100pF.

4. Per JESD 51-5 (1S2P Direct Attach Method).

5. Per JESD 51-3 (1S0P).

6. Specification for packaged product only.
