Half-duplex means the driver and receiver share the same pair of wires — the bus must be turned around (TX enable toggled) between transmit and receive. That makes it a natural fit for multi-drop polling networks where only one node talks at a time. The 100 mV receiver hysteresis gives noise immunity on long cable runs, reducing false triggers from reflections or coupled interference. ## Active lifecycle — no LTB pressure No last-time-buy or obsolescence notice is on file. For a BOM freeze, this part does not force a near-term respin. The CSA+ stays the commercial-grade pick.","metaTitle":"MAX3085CSA+ RS-485/RS-422 Transceiver, 500kbps, Half-Duplex","metaDescription":"Maxim MAX3085CSA+ half-duplex RS-485/RS-422 transceiver. 500kbps data rate, 5V supply, 8-SOIC.
