• Remote Sensor Networks
• Security and Surveillance Systems
• Point-of-Sale (POS) Equipment

Features:

• Half-Duplex RS-485 Transceiver
• Low Power Consumption
• Data Rates up to 10 Mbps
• ±15kV HBM ESD Protection
• Single 5V Supply Operation
• Thermal Shutdown Protection
• Driver Output Short-Circuit Protection
• Receiver Input Hysteresis

Benefits:

• Robust Communication: Provides reliable data transmission in harsh industrial environments due to high ESD protection and noise immunity.
• Energy Efficiency: Low power consumption makes it suitable for battery-powered applications and minimizes overall system power consumption.
• High-Speed Data Transfer: Supports data rates up to 10 Mbps, facilitating fast and efficient communication between devices.
• Enhanced Protection: Features thermal shutdown and short-circuit protection, ensuring the transceiver's longevity and preventing damage from overcurrent or overheating conditions.
• Simplified Integration: Operates from a single 5V supply, simplifying design and integration into existing systems. The receiver input hysteresis further enhances noise rejection, improving overall system reliability.

The SP485EP complies with the TIA/EIA-485 standard. It includes both a driver and a receiver within a single package. The differential driver offers excellent noise immunity and allows for data transmission over considerable distances. The receiver incorporates hysteresis, which enhances noise rejection and reduces the likelihood of false triggering. The SP485EP is available in an 8-pin DIP package.
