1) 0 °C ≤ TC ≤ 70 °C (comm.); -25°C ≤ TC ≤ 85 °C (ext.)All voltages referenced to VSS. VSS and VSSQ must be at same potential.
2) See Table 12 and Figure 4 for overshoot and undershoot definition.
3)
VID is the magnitude of the difference between the input level on CK and the input level on CK.
4) The value of VIX is expected to be equal to 0.5 x VDDQ and must track variations in the DC level.
