The SP3485E is a 3.3V-powered, half-duplex, low-power RS-485 transceiver that fully complies with the TIA/EIA-485 standard. The SP3485E includes one driver and one receiver, both of which can be independently enabled or disabled. When both are disabled, the driver and receiver output a high-impedance state. The SP3485E features a 1/8-unit load, allowing up to 256 SP3485E transceivers to be connected on the same communication bus. It enables error-free data transmission at up to 12Mbps. The SP3485E operates within a voltage range of 3.0V to 3.6V and offers fault protection, overtemperature protection, current-limiting protection, and overvoltage protection.
