Working Principles

The MC3487DR is a differential line driver/receiver IC that operates by amplifying and converting differential input signals into differential output signals. It is designed to transmit and receive data over long distances while maintaining signal integrity and minimizing noise interference.

The IC utilizes differential signaling, where the transmitted data is represented by the voltage difference between two complementary signals. This method provides better noise immunity and allows for longer transmission distances compared to single-ended signaling.

The control inputs (/RE, DE, /DE) enable the user to control the direction of data flow and the receiver enable/disable functions. The built-in protection circuitry guards against electrostatic discharge, enhancing the reliability of the IC.
