MAX211EEWI+T

Drivers, Receivers, Transceivers Overview

The MAX211EEWI+T is a ±15kV ESD-protected, +5V RS-232 transceiver featuring four drivers and five receivers. It operates on a single +4.5V to +5.5V supply using an integrated dual charge pump requiring only four 0.1µF external capacitors. The device supports data rates up to 120kbps with full duplex communication. It includes shutdown and enable control pins for power management and port multiplexing. The component is housed in a 28-pin SOIC package and functions within the -40°C to +85°C industrial temperature range.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high ±15kV HBM ESD protection on all RS-232 pins
• Single +5V supply operation via internal dual charge pump circuitry
• Shutdown mode reduces supply current to typically 1µA
• Enable control allows receiver outputs to enter high-impedance state

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Hand-held equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing from distributors. Confirm the 'E' designation corresponds to the extended -40°C to +85°C temperature range. Ensure the ordering part number matches the 28-SOIC package variant required for the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple driver and receiver channels within a single IC. The integrated charge pump eliminates the need for external bipolar supplies. Verify that the 120kbps maximum data rate meets the application's speed requirements before finalizing the selection.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers manufactured by Analog Devices (Maxim Integrated). The MAX211E variant specifically provides a combination of four drivers and five receivers, distinguishing it from other family members like the MAX202E or MAX232E which offer fewer channels.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX211EWI+ is a parameter-equivalent alternative available from the same manufacturer. Both parts share identical electrical characteristics and pinouts, differing primarily in the reel versus tube packaging configuration.
