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 VCC), the strong pull−down reverts to a weak
current source.
