The ST485EBN is a low power differential line transceiver designed by STMicroelectronics to meet the requirements of RS-485 and RS-422 serial communications. This transceiver is intended for balanced data transmission and complies with both TIA/EIA-485 and TIA/EIA-422 standards. It is particularly suitable for applications where high data rate, low power consumption, and long-distance data transmission are necessary.
Featuring a half-duplex communication capability, it allows for bidirectional data communication on a single pair of wires. The ST485EBN can be used in multi-point networks with up to 32 drivers and receivers on a single bus, making it an excellent choice for complex industrial networks.
Key features of the ST485EBN include:
- Low Quiescent Current: It operates with a very low quiescent current, making it ideal for energy-efficient designs.
- Wide Supply Voltage Range: The device supports a supply voltage range from 5V to 5.5V, providing flexibility in various application environments.
- High Data Rate: Capable of data rates up to 2.5 Mbps, the ST485EBN is suitable for high-speed communication requirements.
- Thermal Shutdown Protection: It includes a thermal shutdown feature that protects the device from damage due to excessive power dissipation.
- Driver Differential Outputs: The device offers driver differential outputs that can handle ±1.5V to ±12V common-mode voltage range.
The ST485EBN is available in a narrow 8-pin plastic DIP package, ensuring compatibility with standard PCB layouts. Its industrial temperature range of -40°C to 85°C guarantees reliable operation under extreme conditions, which is crucial for industrial and outdoor applications.
With its robust design and advanced features, the ST485EBN transceiver from STMicroelectronics is an optimal solution for designers looking to implement reliable data communication in industrial automation, building management systems, and networked devices where efficient and secure data transmission is a priority.
