Notes:
4. Outputs open. Tested at Frequency = 20 MHz.
5. All inputs = VCC – 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. CL = 30 pF for all AC parameters except for tOHZ.
8. CL = 5 pF for tOHZ.
