The S485EC from STMicroelectronics is a high-performance, robust transceiver designed for RS-485 and RS-422 communication protocols. This integrated circuit is engineered to provide bidirectional data communication on multipoint bus transmission lines, making it an ideal choice for industrial, commercial, and telecom applications where reliable data transmission is critical.

Key Features

• Electrical Data Rates: Capable of supporting data rates up to 10 Mbps, the S485EC is suitable for high-speed data transmission environments.
• Extended Common-Mode Range: The device operates over an extended common-mode range of -7V to +12V, enhancing data integrity in electrically noisy environments.
• Thermal Shutdown Protection: With built-in thermal shutdown protection, the S485EC ensures reliable operation by preventing damage due to excessive temperature.
• Driver Differential Output: The transceiver features a driver differential output which exceeds the RS-485 and RS-422 requirements for balanced and unbalanced data transmission.
• Receiver Input Sensitivity: The receiver can detect signals as low as 200 mV over the full common-mode range, providing high sensitivity to incoming data.
• Fail-Safe Receiver: In the event of a loss of input signal (open circuit, idle bus, or shorted bus), the receiver output will remain in a high state, ensuring a fail-safe condition.
