STMICROELECTRONICS RS485 / RS422 Transceiver, 3V to 3.6V, SOIC-8

The STMICROELECTRONICS RS485 / RS422 Transceiver is a high-performance, 3.3V powered device designed for robust serial communication. Operating in a half-duplex configuration, it features one driver and one receiver, delivering data rates of up to 15Mbps. This transceiver is engineered to operate from a single 3V to 3.6V supply without requiring a charge pump, simplifying circuit design and reducing component count.

Offering exceptional durability, the device includes comprehensive ESD protection of ±8 kV contact, ±15 kV air gap, and ±12 kV HBM. It ensures reliable operation in demanding environments with an operating temperature range of -40°C to 85°C. Key protective features include current limiting and thermal shutdown to safeguard the driver against overload conditions. Furthermore, it guarantees a high receiver output state for floating inputs when no signal is present, preventing erroneous data transmission.

The transceiver is fully interoperable with 5V logic and incorporates a low current shutdown mode of 1µA maximum, making it highly power-efficient. Its wide common mode input voltage range of -7V to 12V further enhances signal integrity in noisy electrical environments. With an industry-standard 75176 pinout and the capacity to support up to 64 transceivers on a single bus, it provides a versatile and reliable solution. Housed in a compact SOIC-8 package, this transceiver is ideal for space-constrained applications requiring dependable data transmission.
