Table 1. 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 those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. The DC input voltage on any pin should not be lower than −0.5 V or higher than V
CC
+ 0.5 V. During transitions, the voltage on any pin may
undershoot to no less than −1.5 V or overshoot to no more than V
CC
+ 1.5 V, for periods of less than 20 ns.

4. These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC−Q100
and JEDEC test methods.
5. When not driven, the WP, A0, A1 and A2 pins are pulled down to GND internally. For improved noise immunity, the internal pull−down is relatively
strong; therefore the external driver must be able to supply the pull−down current when attempting to drive the input HIGH. To conserve power,
as the input level exceeds the trip point of the CMOS input buffer (~ 0.5 x V
CC
), the strong pull−down reverts to a weak current source.
