ST485ECDR – Reliable Transceiver for High-Speed Data Transmission

ST485ECDR is an advanced integrated circuit from STMicroelectronics that functions as a serial transceiver (transmitter/receiver) designed for RS-485 standard communication. It is an ideal solution for applications requiring long-distance data transmission and operation in challenging electromagnetic environments, such as industrial systems, automation, and communication networks.

Features:

• Low power consumption: A standby current of only 300 µA ensures energy efficiency and extended system lifespan.
• Wide input voltage range: The device supports voltages from -7 V to 12 V, allowing operation in diverse electrical environments.
• High-impedance mode: The driver enters a high-impedance state in 3-state mode and when powered down, minimizing its impact on the communication bus.
• Signal stability: A typical input hysteresis of 70 mV enables reliable data transmission even in the presence of interference.
• Fast transmission: A propagation delay of 30 ns and a rise/fall time of 5 ns ensure efficient communication.
• Power supply: The device operates at 5 V, facilitating integration with other system components.
• Protections: Current limiting and thermal protection safeguard the driver from overloads. ESD protection up to ±15 kV (HBM) and ±8 kV (IEC-1000-4-2) ensures resistance to electrostatic discharges.
• Multi-device support: Allows up to 256 transceivers to be connected on a single bus, enabling extensive communication networks.

Applications:

• Industrial systems: Ideal for data transmission in industrial networks, automation, and control devices.
• Network communication: Used in applications requiring long-distance communication, such as monitoring and control systems.
• Audio and video systems: Suitable for transmitting audio and video data over long distances.
• Network management: Employed in devices managing and controlling network connections.
• Portable and embedded devices: Applicable in portable or embedded systems where reliable serial communication is required.
