Notes:

1. Output voltage (open drain or open collector) condition = 3 mA sink current.

2. Refer to the MPC8568E PowerQUICC III Integrated Communications Processor Reference Manual for information on the

digital filter used.

3. I/O pins will obstruct the SDA and SCL lines if OVDD is switched off.

Table 47. I2C AC Electrical Specifications

At recommended operating conditions with OVDD of 3.3V ± 5%. All values refer to VIH (min) and VIL (max) levels (see Table 46).
