RS-485/RS-422 transceiver — half-duplex, 250 kbps
The MAX1483CSA+ is a half-duplex transceiver supporting both RS-485 and RS-422 protocols, with a single driver and single receiver on-chip (1/1 configuration). Data rate is rated at 250 kbps, which suits industrial fieldbus links, building automation, and sensor networks where cable lengths run tens to hundreds of metres.
Receiver hysteresis and temperature grade
Receiver hysteresis is 75 mV, which provides noise immunity on long differential pairs — the hysteresis band suppresses chatter from reflections and coupled noise without external filtering. For an indoor control cabinet or office-environment bus node this is sufficient; an industrial or outdoor deployment would need the industrial-temperature variant from the same family.
Supplied in tube packaging — not tape-and-reel — so it arrives in cut-tube format suitable for prototype builds or low-volume production runs.
