Industrial RS485/RS422 link — noise margin and temperature grade
Rated for RS422 and RS485 protocols at 2.5 Mbps, this half-duplex transceiver is sized for industrial fieldbus backplanes, motor-drive comms links, and PLC-to-I/O bridges where the data rate sits below the 10 Mbps ceiling of typical RS485 parts. The 50 mV receiver hysteresis provides a built-in noise margin — on a long twisted-pair run in a factory environment, the 50 mV deadband prevents the output from chattering on ground-shift transients that would toggle a zero-hysteresis receiver. This covers unheated enclosures, outdoor cabinet installations, and the ambient rise inside a sealed panel — the 85°C ceiling matches the typical derating point for most 3.3V CMOS transceivers. The 1/1 driver/receiver count is the standard single-node configuration for point-to-point or multi-drop RS485 with one master and one addressed slave per transaction.
8-SOIC — board-fit and reflow profile
The supplier device package is listed as 8-SOIC, matching the industry-standard SOIC-8 land pattern.
