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. See the last page of this specification for Group A subgroup testing information.
7. 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)).
8. All inputs = VCC – 0.2V, except WCLK and RCLK (which are switching at frequency = 20 MHz). All outputs are unloaded.
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.
