MAX250CPD+

Overview

The MAX250CPD+ is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates at a fixed supply voltage of 5V and supports data rates up to 116 kb/s in full-duplex mode. The device integrates two drivers and two receivers within a single PDIP-14 package designed for through-hole mounting. It features a shutdown mode that reduces the operating supply current to 500 uA. The component is rated for an industrial temperature range from 0°C to +70°C.

Feature Summary

• Integrated dual driver and receiver architecture for full-duplex communication
• Shutdown capability for significant power reduction during idle periods
• Single 5V power supply operation without external charge pumps

Applications

• Industrial equipment requiring isolated serial communication links
• Data acquisition systems with multiple sensor inputs
• Embedded control panels utilizing standard RS-232 protocols

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and environmental compliance status. Confirm availability directly with authorized distributors as stock levels fluctuate. Ensure the procurement channel provides valid traceability for quality assurance purposes before finalizing orders.

Selection Notes

Select this component when a robust, single-supply RS-232 solution is required for through-hole PCB designs. Consider the 116 kb/s speed limit and 500 uA shutdown current when evaluating system power budgets. Verify that the 0°C to +70°C operating range meets the environmental requirements of the target application environment.

Part Context

This part belongs to the MAX250 series of RS-232 interface integrated circuits. It serves as a legacy alternative to newer miniaturized surface-mount options while maintaining compatibility with traditional DIP footprints. The series is characterized by its simplicity and reliability in standard serial communication applications.

Replacement Considerations

Check for direct pin-compatible upgrades such as the MAX232 or MAX233 if higher data rates are needed. Verify that any substitute maintains the same 5V supply requirement and PDIP-14 footprint to ensure mechanical fit.
