With ac parameters, it is assumed that tT = 2 ns. 5. Access times are measured with output reference levels of VOH = 2 V and VOL = 0.8 V. 6. The MAX specifications of tREZ , tCEZ , tWEZ and tOEZ are specified when the output is no longer driven. Data-in should not be driven until one of the applicable maximum specifications is satsified.
