Notes:

1. Functional and tested operating conditions are given in Table 4. Absolute maximum ratings are stress ratings only and

functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause

permanent damage to the device.

2. See Section 9.2, “Power Supply Design and Sequencing” for power sequencing requirements.

3. Bus must be configured in the corresponding I/O voltage mode; see Table 3.

4. Caution: Vin must not exceed OVDD by more than 0.3 V at any time including during power-on reset except as allowed by

the overshoot specifications. Vin may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 2.
