SP3485EN+TD

This device is a 3.3V-powered, half-duplex, low-power RS-485 transceiver that fully complies with the TIA/EIA-485 standard. It integrates one driver and one receiver, both of which can be independently enabled or disabled. When both are disabled, the driver and receiver enter a high-impedance state. The device features 1/8 unit load, allowing up to 256 transceivers to be connected on the same bus, supporting error-free data transmission at rates up to 10Mbps. It operates over a supply voltage range of 3.0~5V and provides fail-safe, over-temperature protection, current-limiting protection, and overvoltage protection.
