The recommended operating voltage range for PCA9703PW,118 is 2.7V to 5.5V.
To ensure reliable communication, make sure to use pull-up resistors on the SCL and SDA lines, and ensure that the clock frequency is within the recommended range of 10 kHz to 400 kHz.
The PCA9703PW,118 can sink or source up to 20mA of current per pin.
To handle bus contention, use a bus arbiter or a multiplexer to ensure that only one device is transmitting on the bus at a time.
The thermal resistance of the PCA9703PW,118 package is typically around 150°C/W.
