RS-485/RS-422 half-duplex transceiver for 5V industrial buses
It runs on a 4.5 V to 5.5 V supply and comes in an 8-pin SOIC package for surface-mount assembly.
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.
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.
