Notes:

5. BUSY pin only.

6. Duration of the short circuit should not exceed 30 seconds.

7. Tested initially and after any design or process changes that may affect these parameters.

8. At f=fMAX, address and data inputs are cycling at the maximum frequency of read cycle of 1/tRC and using AC Test Waveforms input levels of GND to 3V.
