ABSOLUTE MAXIMUM RATINGS Parameter Absolute Maximum Rating Units V to Ground -0.5, +5.0 V DD OUT to Ground -0.3, V + 0.3 V DD Input Current to Any Pin 5 mA Temperature Range -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. 2.
