RS-485/RS-422 transceiver, 250 kbps, half-duplex
The MAX3442EASA+ is a half-duplex transceiver supporting both RS-485 and RS-422 protocols, with a single driver and single receiver on board. The 250 kbps data rate suits industrial fieldbus links where cable length and noise immunity matter more than raw speed — think factory-floor sensor networks or building-automation backbones running over twisted pair. The 25 mV receiver hysteresis cleans up slow edges on long cables, preventing output chatter when the differential signal sits near the threshold. The -40 °C to +125 °C operating temperature covers industrial and automotive ambient extremes — a motor-drive cabinet or an engine-bay ECU sees this band.
Active lifecycle and compliance documentation
For a BOM cost engineer, the active status removes the single-source risk flag that comes with NRND or obsolete parts.
