Working Principles

The MAX1487ECSA+TG002 is an RS-485/RS-422 transceiver that enables reliable data transmission over long distances. It uses differential signaling, where the transmitted data is represented by the voltage difference between two lines (A and B). The receiver detects this voltage difference and converts it back into digital data.

To transmit data, the driver input (DI) receives the digital signal and converts it into a differential voltage on the A and B lines. The driver enable (DE) pin controls the driver's operation. On the receiving end, the receiver output (RO) provides the received data, while the receiver enable (RE) pin controls the receiver's operation.
