7. The product Rev C is identified by letter “C” or dedicated marking code on top of the package.
8. 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.
9. When not driven, the WP, A 0 , A 1 , A 2 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.
