Notes:
4. The voltage on any input or I/O pin cannot exceed the power pin during power-up.
5. TA is the “instant on” case temperature.
6. 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 20 MHz, while data inputs switch
at 10 MHz. Outputs are unloaded. Icc1(typical) = (20 mA + (freq – 20 MHz)*(0.7 mA/MHz)).
7. All inputs = VCC – 0.2V, except WCLK and RCLK (which are at frequency = 0 MHz). All outputs are unloaded.
8. Tested initially and after any design or process changes that may affect these parameters.
9. CL = 30 pF for all AC parameters except for tOHZ.
10. CL = 5 pF for tOHZ.
