MAX211CDW

Drivers, Receivers, Transceivers Overview

The MAX211CDW is a single-supply RS-232 transceiver manufactured by Texas Instruments, housed in a 28-pin SOIC package. It integrates four drivers and five receivers for full-duplex communication with a data rate of 120 kb/s. The device operates on a single 5 V supply (4.5 V to 5.5 V) and includes internal charge pumps to generate positive and negative voltages from the single supply. Key electrical parameters include a propagation delay of 2 µs, a shutdown current of less than 1 µA, and an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Single-supply operation eliminates the need for external dual power rails
• Integrated charge pumps generate required voltage levels internally
• Shutdown mode significantly reduces power consumption

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring serial communication
• Portable battery-powered equipment
• Modems and fax machines

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical specifications. Ensure the component meets the required RoHS compliance standards for your region. Cross-reference the datasheet revision date to ensure access to the most current technical details and errata before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single 5 V supply is available and space constraints prohibit external dual-voltage generation circuits. It is suitable for applications requiring moderate data rates up to 120 kb/s. Compare it against the TRS213 series if a different package type or slight performance variation is needed, ensuring the interface requirements match the system design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX213 family of RS-232 transceivers, which are designed for low-power, single-supply applications. The MAX211 variant specifically offers a compact solution for systems needing multiple transmit and receive lines without the complexity of external capacitors for voltage generation beyond the standard charge pump requirements.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS213IDBR is a documented equivalent from Texas Instruments offering similar functionality in a 28-SSOP package. Verify that the package footprint differences between SOIC and SSOP are accommodated in the PCB layout before substitution.
