PCA9545CPW,118 Frequently Asked Questions (FAQ)
-
The PCA9545CPW,118 can support I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
-
To configure the PCA9545CPW,118 in dual-bus mode, you need to connect the SCL and SDA pins of the two buses to the corresponding pins on the PCA9545CPW,118, and then use the EN pins to enable or disable each bus.
-
The PCA9545CPW,118 can drive capacitive loads up to 400 pF, but it's recommended to limit it to 100 pF for reliable operation.
-
Yes, the PCA9545CPW,118 can switch between multiple I2C buses with different voltage levels, but you need to ensure that the voltage levels are within the recommended operating range of the device.
-
The PCA9545CPW,118 can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
