It runs on a 4.5 V to 5.5 V supply and comes in an 8-pin SOIC package for surface-mount assembly. The 70 mV receiver hysteresis improves noise immunity on long cable runs typical in factory automation, building management, and instrumentation networks. ## 250 kbps data rate — matched to fieldbus timing At 250 kbps this transceiver is sized for Modbus RTU, BACnet MS/TP, and similar half-duplex fieldbuses that top out at that rate. The 70 mV hysteresis on the receiver input filters out noise picked up over twisted-pair runs, reducing false start-bit detection in electrically noisy environments like motor drives and PLC cabinets. ## Active lifecycle — no obsolescence risk for new builds No last-time-buy or end-of-life notice applies. For dual-sourcing resilience, the ADM483ARZ (tube-packaged sibling) is a direct functional equivalent with the same half-duplex RS-485/RS-422 interface, 250 kbps data rate, and 70 mV hysteresis — the only difference is the shipping medium.","metaTitle":"ADM483EAR-1REEL RS-485/RS-422 Transceiver, 250kbps, SOIC-8","metaDescription":"ADM483EAR-1REEL half-duplex RS-485/RS-422 transceiver, 250kbps data rate, 5V supply, SOIC-8 package.
