Working Principles

The ADM3074EYRZ-REEL7 is a half-duplex transceiver that uses differential signaling to transmit and receive data. It operates based on the RS-485/RS-422 standards, which provide robust communication over long distances. The driver section converts the logic-level input signals into differential voltages on the bus, while the receiver section converts the differential voltages back into logic-level signals. The DE and RE pins control the direction of data flow by enabling or disabling the driver and receiver, respectively.
