This device includes open-drain CMOS outputs. Open-drain outputs can only drive the output low. When in the high logical state, open-drain outputs are in a high-impedance state. The drive capability of this device can create fast edges into light loads, so consider routing and load conditions to prevent ringing. Additionally, the outputs of this device are capable of driving larger currents than the device can sustain without being damaged. Limit the device output power to avoid damage due to overcurrent. Follow the electrical and thermal limits defined in the Absolute Maximum Ratings at all times.

When placed into the high-impedance state, the output neither sources nor sinks current, with the exception of minor leakage current as defined in the Electrical Characteristics table. In the high-impedance state, the output voltage is not controlled by the device and is dependent on external factors. If no other drivers are connected to the node, then this is known as a floating node and the voltage is unknown. A pullup resistor can be connected to the output to provide a known voltage at the output while the output is in the high-impedance state. The value of the resistor depends on multiple factors, including parasitic capacitance and power consumption limitations. Typically, use a 10kΩ resistor to meet these requirements.

Leave unused open-drain CMOS outputs disconnected.
