STMicroelectronics RS422 / RS485 Low Voltage Transceiver, 3V-3.6V, SOIC-8

The STMicroelectronics Low Voltage Transceiver is a highly reliable RS-485/RS-422 driver and receiver designed for robust communication systems. Operating from a single 3.3V supply (ranging from 3V to 3.6V), this transceiver requires no charge pump and is fully interoperable with 5V logic, making it versatile for mixed-voltage environments.

This device features a half-duplex configuration with one driver and one receiver, supporting a guaranteed data rate of up to 15Mbps. It includes advanced protection features such as ±15kV ESD protection (IEC 61000-4-2 air discharge), short-circuit current limiting, and thermal shutdown circuitry. The thermal shutdown places the driver outputs into a high-impedance state to prevent excessive power dissipation. Additionally, it guarantees a high receiver output state for floating inputs when no signal is present.
