Notes:
1.
Exceeding the absolute maximum rating may damage the device.
2.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5kΩ in series with 100pF.
3.
The device is not guaranteed to function outside its operating rating.
4.
If VBIAS ≤ 3.6V, then VIN(MAX) = VBIAS.
5.
If VBIAS ≤ 4V, then VDDQ(MAX) = 2 × (VBIAS − 2.2V). If VBIAS > 4V, then VDDQ(MAX) = 3.6V.
6.
Specification for packaged product only.
