MAX213EEWI+

Drivers, Receivers, Transceivers Overview

The MAX213EEWI+ is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +4.5V to +5.5V supply and integrates four drivers and five receivers. The device supports data rates up to 120kbps and features ±15kV ESD protection on all RS-232 inputs and outputs. It utilizes an internal charge pump to generate the required ±10V levels, eliminating the need for external bipolar supplies. The component includes shutdown and enable control pins for power management and is housed in a 28-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high ±15kV HBM ESD protection on RS-232 I/Os
• Internal charge pump eliminates external bipolar supply requirements
• Low-power shutdown mode with awake-in-shutdown receiver capability

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EWI+' against official documentation to confirm the 28-pin SOIC package and industrial temperature range (-40°C to +85°C). Ensure compatibility with existing board layouts regarding pin configurations and capacitor requirements for the integrated charge pump circuitry.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD protection and single-supply operation. The MAX213E variant specifically offers two receivers that remain active during shutdown, enabling wake-up functionality. Verify that the 120kbps data rate meets system timing requirements and that the 28-pin SOIC footprint fits the design constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers. The 'E' designation indicates enhanced ESD protection compared to standard versions. The MAX213E is distinguished within the family by its dual awake-in-shutdown receivers and specific enable/shutdown logic polarity.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX211EEWI+ is a parameter-equivalent alternative within the same family, differing primarily in the absence of awake-in-shutdown receivers. Other family members like the MAX232EEWI+ offer different driver/receiver counts.
