Notes:
8. Resistor values for VCCQ = 5V are: R1 = 1179Ω and R2 = 868Ω. Resistor values for VCCQ = 3.3V are R1 = 317Ω and R2 = 348Ω.
9. Unless otherwise noted, test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output
loading of the specified IOL/IOH and load capacitance. Shown in (a) and (b) of AC Test Loads.
10. Do not use the burst mode, if device operates at a frequency above 50 MHz.
11. tCSOZ, tEOZ, and tWEOZ are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ± 500 mV from steady-state voltage.
12. At any given voltage and temperature, tWEOZ min. is less than tWEOV min.
