1. ABSOLUTE MAXIMUM RATINGS Parameter Absolute Maximum Rating Units
VDD to Ground -0.5, +5.0 V OUT to Ground -0.3, VDD + 0.3 V Input Current to Any Pin ±5 mA Storage Temperature -40 to +100 °C Operating Temperature -40 to +100 °C Stresses exceeding these “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only. Functional operation at these or any other conditions beyond those indicated under “Acoustic & Electrical Specifications” is not implied. Exposure beyond those indicated under “Acoustic & Electrical Specifications” for extended periods may affect device reliability.
