PCA9548ADBR Frequently Asked Questions (FAQ)
-
The PCA9548ADBR can support I2C bus frequencies up to 400 kHz, but it's recommended to limit the frequency to 100 kHz for reliable operation.
-
To configure the PCA9548ADBR in dual-bus mode, connect the SCL/SDA pins of the two buses to the corresponding pins on the PCA9548ADBR, and use the EN pin to select which bus is active. See the datasheet for specific pin connections and control logic.
-
The PCA9548ADBR can drive bus capacitances up to 400 pF, but it's recommended to limit the capacitance to 200 pF for reliable operation.
-
Yes, the PCA9548ADBR can switch between two I2C buses with different voltage levels, but the voltage difference should not exceed 1.5 V. Additionally, ensure that the voltage levels are within the recommended operating range of the PCA9548ADBR.
-
Ensure that the PCA9548ADBR is powered from a stable voltage source, and that the power-on reset (POR) circuit is properly connected. The POR circuit should be connected to a capacitor and a pull-up resistor to ensure a clean reset signal.
