MAX232EIDW

Overview

The MAX232EIDW is an RS-232 transceiver from the MAX232E series, manufactured by Texas Instruments. It features two drivers and two receivers for full-duplex communication with a data rate of 250 kb/s. Operating on a single 5 V supply (4.5 V to 5.5 V), it draws 10 mA. The device provides 15 kV ESD protection and operates between -40°C and +85°C. Packaged in SOIC-16, it has a propagation delay of 0.5 µs and lacks a shutdown function.

Feature Summary

• Integrated charge pump eliminates external voltage conversion requirements
• High electrostatic discharge tolerance protects sensitive interfaces
• Single-supply operation simplifies power design

Applications

• RS-232 serial port implementations
• Modem interface circuits
• Industrial control systems requiring robust communication

Procurement Notes

Verify component authenticity through authorized channels. Confirm package integrity upon receipt. Check datasheet revisions for updated electrical characteristics. Ensure storage conditions meet manufacturer specifications to prevent degradation.

Selection Notes

Select this variant for applications requiring industrial temperature range and higher data rates compared to standard versions. Verify pin compatibility with existing layouts. Consider the SOIC-16 footprint constraints during PCB design.

Part Context

Part of the MAX232 family, this component serves as a line driver and receiver for RS-232 standards. It bridges microcontroller logic levels to RS-232 voltages, enabling reliable serial data exchange in embedded systems.

Replacement Considerations

MAX232IDWR offers identical functionality in tape-and-reel packaging. MAX232EIDWG4 is a compatible alternative with similar specifications.
