Notes:

4. Outputs open. Tested at Frequency = 20 MHz.

5. All inputs = V_CC– 0.2V, except WCLK and RCLK, which are switching at 20 MHz.

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

7. C_L= 30 pF for all AC parameters except for t_OHZ

8. C_L= 5 pF for t_OHZ
