MAX250CSD

Overview

The MAX250CSD is a CMOS RS-232 transceiver designed for single-supply operation. It integrates two drivers and two receivers within a 14-pin SOIC package. The device supports full-duplex communication with data rates up to 116 kb/s. It operates on a single +5V power supply and features a low-power shutdown mode that reduces current consumption to 500 uA. The component complies with EIA/TIA-232-C and V.28/V.24 interface standards.

Feature Summary

• Integrates dual drivers and dual receivers in a compact surface-mount package
• Operates from a single +5V power supply without requiring negative voltages
• Includes a dedicated shutdown pin to minimize power consumption during idle periods

Applications

• Industrial control systems requiring isolated serial communication
• Data communication equipment operating in high-noise environments
• Analog circuit interfaces needing reliable RS-232 signal transmission

Procurement Notes

Verify the specific suffix 'CSD' against the manufacturer's official documentation to confirm the exact temperature range, package type, and RoHS compliance status. Ensure the ordering information matches the required industrial specifications before finalizing procurement decisions.

Selection Notes

Select this component when a single-supply RS-232 solution is required for space-constrained designs. Consider the 116 kb/s data rate limit and the absence of integrated ESD protection when evaluating system requirements. Verify compatibility with external isolation components such as optocouplers and transformers if galvanic isolation is necessary.

Part Context

The MAX250CSD belongs to the MAX250/MAX251 family of low-cost, high-integration isolated RS-232 driver and receiver chips. This series simplifies interface design by combining logic signal processing and optical coupling interfaces into a cohesive solution for standard serial communications.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements may differ in isolation capabilities or drive strength.
