Notes:
5. See the last page of this specification for Group A subgroup testing information.
6. Test no more than one output at a time for not more than one second.
7. Outputs open. Tested at Frequency = 20 MHz.
8. All inputs = VCC – 0.2V, except WCLK and RCLK, which are switching at 20 MHz.
9. Tested initially and after any design or process changes that may affect these parameters.
10. CL = 30 pF for all AC parameters except for tOHZ.
11. CL = 5 pF for tOHZ.
