MAX211ECAI+T

Drivers, Receivers, Transceivers Overview

The MAX211ECAI+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 120 kbps 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 20 mA and shutdown current of 1 µA. The component utilizes a 28-pin SSOP 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 standby power
• Hand-held diagnostic tools
• Portable computing devices

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AI' corresponds to the 28-pin SSOP package and commercial temperature grade (0°C to +70°C) as defined in the official ordering information. Confirm that the '+T' designation indicates tape-and-reel packaging if reel quantity is required for assembly. Cross-reference the manufacturer's latest datasheet revision to ensure pinout compatibility with existing designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and multiple serial channels are needed. The integrated charge pump simplifies board layout by removing the need for external voltage inverters. Ensure the application environment remains within the commercial temperature limits; industrial grade variants require different suffixes. Verify that the 120 kbps maximum data rate meets the system communication speed requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers designed for single-supply applications. The 'E' suffix denotes enhanced ESD protection compared to standard versions. The MAX211 variant specifically offers four drivers and five receivers, providing more I/O lines than the MAX202 or MAX232 while maintaining similar footprint constraints.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX211EWI+ serves as a parameter-equivalent alternative in the SOIC-28 package. Other family members like the MAX241E offer identical electrical performance but may differ in capacitor requirements or pin configurations. Verify package dimensions and thermal characteristics before substitution.
