5V half-duplex RS-485 transceiver — commercial temp range
Receiver hysteresis and bus noise immunity
The 50 mV of receiver hysteresis is a practical feature for RS-485 links running at moderate data rates over twisted-pair cabling. It prevents output chatter when the differential signal is slow or the bus is idle. For longer runs or noisier environments, compare against parts with higher hysteresis or fail-safe biasing — but for a standard 5V half-duplex node inside a cabinet, this is a solid fit.
