MAX211CDWR

Drivers, Receivers, Transceivers Overview

The MAX211CDWR is a Texas Instruments integrated circuit featuring five line drivers and five receivers for RS-232 communication. It operates on a single 5-V supply and includes internal charge pumps to generate positive and negative voltages from the 5-V input, eliminating the need for external components. The device provides bus-pin electrostatic discharge (ESD) protection exceeding ±15 kV using the human-body model. It meets or exceeds TIA/EIA-232-F and ITU V.28 standards, supporting data rates up to 120 kbps in full-duplex mode.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates external capacitors for voltage generation
• High ESD protection rating of ±15 kV on all bus pins
• Compliance with TIA/EIA-232-F and ITU V.28 interface standards

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring robust serial communication
• Modem interfaces and telecommunications equipment
• Portable battery-powered instruments needing simplified power management

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package marking and date code against the official Texas Instruments datasheet to confirm authenticity. Ensure the ordering suffix matches the required tape and reel configuration for automated assembly processes. Cross-reference the component markings with manufacturer documentation to prevent counterfeit substitution.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple independent RS-232 channels without external voltage generation circuitry. It is suitable for applications demanding high ESD immunity and compliance with standard serial interface protocols. Consider the 28-SOIC package constraints regarding thermal dissipation and board space availability.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX211 family of multichannel RS-232 transceivers. It shares functional similarities with other devices in the series but is distinguished by its specific pinout and channel count. The CDWR suffix indicates a commercial temperature range and tape-and-reel packaging format.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the MAX211CDE4 and MAX211IDWR variants, which offer identical functionality with different temperature ranges or packaging options. Verify pin compatibility before replacing.
