Working Principles

The MAX3190EEUT+T is designed as an RS-485/RS-422 transceiver. It operates by converting the differential signals from the driver input (DI) into a balanced output on the receiver output (RO). The driver enable (DE) and receiver enable (RE) pins control the direction of data flow. When DE is high and RE is low, the device operates in transmit mode, allowing data transmission from DI to RO. Conversely, when DE is low and RE is high, the device operates in receive mode, enabling data reception on RO.
