AC Read Characteristics Notes
(1) WE is High for Read Cycle.
(2) All read cycle timing is referenced from the last valid address to the first transition address.
(3) tCHZ and tOHZ are defined as the time at which the outputs achieve open circuit conditions and are not
referenced to output voltage levels.
(4) At any given temperature and voltage condition, tCHZ (max) is less than tCLZ (min) both for a given module
and from module to module.
(5) These parameters are sampled and not 100% tested.
