ElecSuper SP3485EN-L/TR

SP3485EN-L/TR is a half-duplex, low-power RS-485 transceiver that fully complies with TIA/EIA-485 standard requirements, featuring a 3.0V~5.5V wide supply voltage range, bus port ESD protection up to 15kV HBM, and a bus voltage tolerance of ±15V. It integrates one driver and one receiver, both independently enable/disable controllable. When both are disabled, the driver and receiver outputs enter a high-impedance state. With 1/8 unit load, up to 256 SP3485EN-L/TR transceivers can be connected in parallel on the same communication bus. Error-free data transmission at up to 14Mbps is supported. Operating at 3.3V, the device provides fail-safe, current limiting, and overvoltage protection.
