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. The DC input voltage on any pin should not be lower than â0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may
undershoot to no less than â1.5 V or overshoot to no more than VCC + 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 AECâQ100
and JEDEC test methods.
5. When not driven, the WP, A0, A1, A2 pins are pulled down to GND internally. For improved noise immunity, the internal pullâdown is relatively
strong; therefore the external driver must be able to supply the pullâdown 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 VCC), the strong pullâdown reverts to a weak current source.
