PCA9541AD/03,118 Frequently Asked Questions (FAQ)
-
The PCA9541AD/03,118 can support I2C bus frequencies up to 400 kHz, but it's recommended to limit the frequency to 100 kHz for reliable operation.
-
Yes, the PCA9541AD/03,118 can switch between multiple I2C buses with different voltage levels, but the voltage on the SCL and SDA pins must not exceed the VCC supply voltage of the device.
-
To ensure correct switching, the control logic should assert the enable signal (EN) before sending the I2C commands, and de-assert EN after the I2C transaction is complete. Additionally, the control logic should ensure that the I2C bus is idle before switching to a different bus.
-
The PCA9541AD/03,118 can drive up to 400 pF of capacitance on the I2C bus, but it's recommended to limit the capacitance to 200 pF for reliable operation.
-
Yes, the PCA9541AD/03,118 can switch between I2C buses with different clock stretching requirements, but the control logic should ensure that the clock stretching requirements of the target device are met.
