250 kbps RS-485 transceiver for industrial multi-drop buses
The SN65HVD72DRBT: With one driver and one receiver, it connects directly to a two-wire RS-485 bus — the standard topology for industrial sensor networks, PLC links, and building automation backplanes.
Receiver hysteresis and noise margin on long cable runs
The 80 mV receiver hysteresis filters out noise picked up on long twisted-pair cables — a common failure point in factory-floor RS-485 runs where ground potential differences inject common-mode noise. At 250 kbps the bus can span several hundred metres with proper termination; the hysteresis prevents false start bits when the differential signal sits near the switching threshold.
Active lifecycle and compliance status
ROHS3 compliant, with no exemptions that would restrict shipping to EU, UK, or other regulated markets.
