MAX211ECWI+T

Drivers, Receivers, Transceivers Overview

The MAX211ECWI+T is a single-supply RS-232 transceiver from the MAX202E–MAX213E family, manufactured by Analog Devices Inc./Maxim Integrated. It integrates four drivers and five receivers with an internal charge pump for +5V operation. The device supports data rates up to 120kbps and features ±15kV ESD protection on all pins. It operates within a commercial temperature range of 0°C to +70°C. Electrical characteristics include a typical supply current of 20mA in normal mode and 1µA in shutdown. The component utilizes a 28-pin Wide SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge-pump circuitry to generate required voltage levels from a single +5V supply, eliminating external bipolar power requirements.
• Provides robust ±15kV Human Body Model ESD protection on driver outputs and receiver inputs to withstand harsh handling environments.
• Includes dedicated enable and shutdown control pins to manage power consumption and facilitate port multiplexing via high-impedance states.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power serial communication
• Hand-held diagnostic tools and portable instrumentation
• Notebook computers and mobile devices with frequent port connections

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this part number. Confirm that the 'C' designation aligns with the required commercial operating temperature range of 0°C to +70°C for your application environment. Ensure compatibility with the 28-pin Wide SOIC footprint during PCB layout verification.

Drivers, Receivers, Transceivers Selection Notes

Select this variant over the EE version if the application operates strictly within the commercial temperature range of 0°C to +70°C. The EC suffix denotes the specific temperature grade, while the T suffix specifies reel packaging. Verify that the four-driver and five-receiver configuration matches the system's signal routing requirements compared to other members of the MAX211E family.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX202E–MAX213E family of RS-232 transceivers designed for single-supply applications. The MAX211E specifically offers a high channel count with four drivers and five receivers. The 'E' suffix indicates enhanced ESD protection capabilities compared to standard versions, making it suitable for rugged environments where static discharge is a concern.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX211EEWI+ serves as a direct functional substitute with identical electrical specifications but differs in the operating temperature range (industrial -40°C to +85°C). Other family members like the MAX213E offer similar functionality but include awake-in-shutdown receivers and reversed control pin logic.
