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 0 , A 1 , A 2
and WP should not exceed V CC + 1 V for more than 20 ns, while voltage on the I 2 C bus pins, SCL and SDA, should not exceed the absolute
maximum ratings, irrespective of V CC .
