†
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to GND.
2. Absolute negative voltage on these terminals should not go below –0.5 V.
3. The human body model is a 100-pF capacitor discharged through a 1.5-kΩ resistor into each terminal. Devices are ESD sensitive.
Handling precautions are recommended.
