The UA96173PC is typically packaged in a DIP (Dual In-line Package). It generally operates from a single 5V supply. It features separate driver and receiver enable pins for flexible control of the data transmission direction. The differential output impedance is designed to match the characteristic impedance of the transmission line, minimizing reflections and signal distortion. External termination resistors are typically required to match the impedance of the transmission line and prevent reflections, ensuring optimal signal quality.
