The PCA9675PW,118 can support I2C bus frequencies up to 400 kHz.
Yes, PCA9675PW,118 can be used as a level shifter for 5V to 3.3V or 1.8V, but it's essential to ensure that the input voltage does not exceed the maximum rating of the device.
To configure the PCA9675PW,118 for bidirectional voltage translation, connect the VCC pin to the higher voltage supply, and the VCCX pin to the lower voltage supply. Then, connect the data lines (A0-A7) to the corresponding data lines of the higher and lower voltage devices.
The PCA9675PW,118 can sink or source up to 8 mA of current per I/O pin.
Yes, PCA9675PW,118 is compatible with other I2C bus extenders or repeaters, but it's essential to ensure that the devices are properly connected and configured to avoid bus conflicts.
