Notes:
1. The min VILand max VIH values are based on the respective min and max OVIN values found in Table 3.
2. The output voltage (open drain or open collector) condition = 3 mA sink current.
3. See the chip reference manual for information about the digital filter used.
4. I/O pins obstruct the SDA and SCL lines if OVDD is switched off.
5. For recommended operating conditions, see Table 3.
This table provides the DC electrical characteristics for the I2C interfaces operating at
1.8V.
