ABSOLUTE MAXIMUM RATINGS Parameters Ratings Units Storage Temperature 65 to +150 C Voltage on any pin with respect to Ground (Note 1) 0.5 to +6.5 V Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. During input transitions, voltage undershoot on any pin should not exceed 1 V for more than 20 ns. Voltage overshoot on pins A , A , A 0 1 2 2 and WP should not exceed V + 1 V for more than 20 ns, while voltage on the I C bus pins, SCL and SDA, should not exceed the absolute CC maximum ratings, irrespective of V .
