For 8 channel I2C mux we would like to know if we could connect VDD to 2.5V and connect one of the downstream to 1.8V?
Configuration we are planning to use.
- Upstream I2C bus-3.3V
- 3 Downstream channels- 1.8V
- 5 Downstream channels- 3.3V
From the AN262-2 Figure 7, it is not clear if 2.5V VDD can support 1.8V I2C bus
