Fig.3 Tri-State measurement
Note20.Valid Delay Measurement is made from the VDDQ/2 on the input waveform to the VDDQ/2 on the output waveform.
Input waveform should have a slew rate of faster than or equal to 1V/ns.
Note21.Tri-state toff measurement is made from the VDDQ/2 on the input waveform to the output waveform moving 20%
from its initial to final Value VDDQ/2.
Note:the initial value is not VOL or VOH as specified in DC ELECTRICAL CHARACTERISTICS table.
Note22. Tri-state ton measurement is made from the VDDQ/2 on the input waveform to the output waveform moving 20%
from its initial Value VDDQ/2 to its final Value.
Note:the final value is not VOL or VOH as specified in DC ELECTRICAL CHARACTERISTICS table.
Note23.Clocks,Data,Address and control signals will be tested with a minimum input slew rate of faster than or equal to 1V/ns.
