MAX250EPD+

Overview

The MAX250EPD+ is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates at a single +5V supply voltage and supports data rates up to 116kbps in full-duplex mode. The device integrates two drivers and two receivers within a 14-pin PDIP package designed for through-hole mounting. Key electrical specifications include a maximum operating temperature of +85°C, a minimum operating temperature of -40°C, and a typical quiescent supply current of 500µA. The component includes a shutdown feature for power management but does not incorporate built-in ESD protection circuitry.

Feature Summary

• Integrated dual driver and receiver architecture for complete RS-232 signal conversion
• Single +5V power supply operation with low standby current consumption
• Hardware shutdown control pin for reducing power dissipation during idle periods

Applications

• Industrial equipment requiring isolated serial communication links
• Embedded systems utilizing standard RS-232 protocols
• Data acquisition modules interfacing with legacy serial peripherals

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and environmental compliance status. Ensure that the procurement channel provides valid traceability records for the component batch. Confirm availability constraints as distribution channels may vary by region. Cross-reference the datasheet revision date to ensure compatibility with current design requirements before finalizing purchase orders.

Selection Notes

Select this component when a robust, single-supply RS-232 interface is required without integrated electrostatic discharge protection. Evaluate the thermal performance limits relative to the intended operating environment, specifically noting the absence of internal ESD safeguards. Compare the 116kbps speed capability against system timing requirements. Verify that the through-hole packaging aligns with the printed circuit board layout and assembly processes.

Part Context

This part belongs to the MAX250 series of RS-232 transceivers produced by Maxim Integrated, now part of Analog Devices. The series focuses on providing reliable serial communication interfaces for industrial and commercial applications using standard voltage levels. The EPD designation indicates a specific plastic dual in-line package variant suitable for general-purpose prototyping and manufacturing.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same product family. Verify functional equivalence regarding voltage levels and data rates before substituting.
