SP485EN General Description
The SP485EN is a half-duplex transceiver, commonly used in RS-485 communication networks. It operates on a 5V power supply and has a low-power shutdown mode, making it suitable for battery-powered applications. This device features a fail-safe receiver, ensuring a high level of noise immunity and reliable data transmission over long distances, up to 1200 meters at speeds up to 250kbps. With its wide common-mode range, it can tolerate ground shifts and noise commonly encountered in industrial environments. The SP485EN incorporates thermal shutdown protection, guarding against excessive temperature conditions. It also includes short-circuit and overvoltage protection, enhancing robustness in harsh operating conditions. Additionally, it comes in various package options, including SOIC and PDIP, providing flexibility for different PCB layouts and assembly processes.
