PCB Symbol, Footprint & 3D Model

The PCA9539DBR can support I2C bus frequencies up to 400 kHz.
The PCA9539DBR can be configured to operate in 8-bit or 16-bit mode by setting the MODE pin high or low, respectively, during power-up.
The PCA9539DBR can sink or source up to 25 mA of current on each output pin.
The PCA9539DBR can be reset by pulling the RESET pin low for at least 1 ms.
