Notes:

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

2. CB = capacitance of one bus line in pF.

3. Refer to the

MPC8360E Integrated Communications Processor Family Reference Manual for information on the digital filter

used.

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

Table 45. I2C AC Electrical Specifications

All values refer to VIH (min) and VIL (max) levels (see Table 44).
