• Low Power Consumption
• Data Rates up to 10Mbps
• ±15kV HBM ESD Protection
• Single 5V Supply
• Thermal Shutdown Protection
• Driver Output Short-Circuit Protection
• Receiver Input Hysteresis

Benefits:

• Reliable Communication: Offers robust data transmission in noisy environments thanks to high ESD protection and receiver hysteresis.
• Energy Efficient: Low power consumption makes it suitable for battery-powered applications or systems where energy conservation is critical.
• High-Speed Data Transfer: Supports data rates up to 10Mbps, enabling fast and efficient communication.
• Protection Against Damage: Built-in thermal shutdown and current limiting features protect the device from overheating and overcurrent conditions, ensuring long-term reliability.
• Ease of Integration: Single 5V supply simplifies design and integration into existing systems. The receiver input hysteresis enhances noise rejection for improved system reliability.

The SP486CS is designed to meet the TIA/EIA-485 standard. It incorporates both a driver and a receiver in a single package. The differential driver provides high noise immunity and facilitates communication over long distances. The receiver includes hysteresis to improve noise rejection and prevent false triggering. It's available in an 8-pin SOIC package.
