Detailed description
SP485EEN-L/TR IC
The SP485EEN-L/TR is a high-performance, low-power transceiver designed for serial communication in RS-485 and RS-422 standards. This component is engineered for operation in demanding industrial environments, providing stable data transmission over long distances while maintaining high electromagnetic noise immunity. By integrating the driver and receiver in a single SO-8 package, it is ideal for applications requiring reliable information exchange in multipoint networks.
Key Features and Specifications of SP485EEN-L/TR
The SP485EEN-L/TR model offers full industrial standard compatibility and can operate over an extended temperature range. It is a half-duplex device, allowing bidirectional data transmission using a single pair of wires. The main technical parameters of this transceiver are:
- Standards: Compatible with RS-485 and RS-422.
- Data Rate: Supports transmission speeds up to 5 Mbps.
- Supply Voltage: Standard 5 V (range 4.75V to 5.25V).
- Bus Loading: Supports up to 32 unit loads on the bus.
- Protection: Built-in output short-circuit and thermal protection.
- Current Consumption: Low standby current (typically 500µA), ideal for energy-sensitive systems.
- Package: SO-8, suitable for surface-mount (SMD) assembly.
Advanced output drivers with limited slew rate help reduce EMI in similar series, but the SP485EEN model prioritizes maximum performance up to 5 Mbps, making it ideal for high-speed automation networks.
Typical Applications of SP485EEN-L/TR
Thanks to its high noise immunity and ability to operate over long transmission lines, the SP485EEN-L/TR is commonly used in professional communication systems, such as:
- Industrial automation networks (Modbus, Profibus buses),
- Security and monitoring systems (PTZ camera control, access readers),
- Smart energy meters and remote utility monitoring systems,
- Professional lighting controllers (DMX512 protocols),
- Processor-to-processor communication in distributed control systems.
