Working Principles

The MAX1486EUB+T is a half-duplex transceiver designed for RS-485/RS-422 communication. It operates by converting the differential signals from the driver input (DI) into balanced signals on the driver output (Y, Z). Similarly, it converts the balanced signals received on the receiver input (A, B) into differential signals on the receiver output (RO).

The driver enable (DE) and receiver enable (/RE) pins control the direction of data transmission. When DE is high and /RE is low, the device is in transmit mode, allowing data to be sent from DI to the driver output. Conversely, when DE is low and /RE is high, the device is in receive mode, enabling data reception from the receiver input to RO.
