Notes:
1. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating
2. The device is not guaranteed to function outside its operating rating.
3. IC devices are inherently ESD sensitive. Handling precautions required. Human body model rating: 1.5k in series with 100pF.
4. Specification for packaged product only.
5. Connect V
