Notes:
4. VCC Range for commercial -10 ns is 3.3V ±150mV.
5. Input signals switch from 0V to 3V with a rise/fall time of less than 3 ns, clocks and clock enables switch at maximum frequency of 20 MHz, while data inputs
switch at 10 MHz. Outputs are unloaded.)
6. All inputs = VCC − 0.2V, except WCLK and RCLK (which are at frequency = 0 MHz). All outputs are unloaded.
7. Tested initially and after any design or process changes that may affect these parameters.
8. CL = 30 pF for all AC parameters except for tOHZ.
9. CL = 5 pF for tOHZ.
