RS-422/RS-485 transceiver with 250 kbps and full-duplex capability
It is designed for industrial serial communication links where balanced differential signalling provides noise immunity over cable runs of several hundred metres. The 250 kbps data rate suits applications like programmable logic controllers, motor drives, and building automation panels that operate at moderate baud rates.
The supply range of 4.5 V to 5.5 V ties this part to a 5 V nominal rail. It is not 3.3 V compatible, so a mixed-voltage system needs a separate 5 V supply or a level translator. The 100 mV receiver hysteresis provides clean switching in noisy environments, reducing false edge counts on long cable runs.
This is a clean signal for BOM planning: no forced redesign due to obsolescence in the near term. ROHS3 compliance also holds, so it ships without lead or restricted halogens.
