NOTES:
1. In setup and hold times, write refers to either any SBx and SW or SGW is low.
2. Chip enable is defined as SE1 low, SE2 high, and SE3 low whenever ADSP or ADSC is asserted.
3. All read and write cycle timings are referenced from K or G.
4. Tested per AC Test Load (Figure 2).
5. Measured at ± 200 mV from steady state. Tested per High–Z Test Load (Figure 2).
6. This parameter is sampled and not 100% tested.
7. At any given voltage and temperature, tKHQZ (Max) is less than tKHQX1 (Min) for a given device and from device to device.
