Key Featrues
±50V Isolation: The MAX3250 provides ±50V isolation between the RS-232 side and the logic side, effectively breaking ground loops caused by high common-mode voltages. This feature enhances performance in noisy industrial environments and prevents damage from accidental short circuits to high-voltage power buses, ensuring reliable communication.
250kbps Guaranteed Data Rate: With a guaranteed data rate of 250kbps, the MAX3250 ensures high-speed data transmission, making it suitable for applications requiring fast and efficient communication, such as industrial control systems and diagnostic ports.
Shutdown Mode for Multiple Interfaces: The device includes a shutdown mode that allows multiple communication interfaces (e.g., IrDA, RS-232, RS-485) to connect to the same UART. In shutdown, it consumes only 20µA of supply current and provides high-impedance outputs, improving power efficiency and flexibility in multi-interface systems.
Inductorless/Transformerless Design: The MAX3250's inductorless and transformerless design simplifies EMI compliance, reducing the complexity and cost of the system design. This makes it an ideal choice for space-constrained applications where EMI compliance is critical.
Low-Cost Replacement for Opto-Isolated Transceivers: The MAX3250 offers a cost-effective alternative to traditional opto-isolated transceivers while maintaining high performance and reliability. This makes it an attractive option for budget-sensitive projects without compromising on quality or functionality.
