Notes:
7. Part (a) of AC Test Loads and Waveforms is used for all parameters except tER and tEA(+). Part (b) of AC Test Loads and Waveforms is used for tER. Part (c) of AC Test
Loads and Waveforms is used for tEA(+).
8. Min. times are tested initially and after any design or process changes that may affect these parameters.
9. The test load of (a) of AC Test Loads and Waveforms is used for measuring tEA(-). The test load of (c) of AC Test Loads and Waveforms is used for measuring tEA(+) only.
Please see (e) of AC Test Loads and Waveforms for enable and disable test waveforms and measurement reference levels.
10. This parameter is measured as the time after output disable input that the previous output data state remains stable on the output. This delay is measured to
the point at which a previous HIGH level has fallen to 0.5V below VOH min. or a previous LOW level has risen to 0.5V above VOL max. Please see (e) of AC Test Loads
and Waveforms for enable and disable test waveforms and measurement reference levels.
