MAX213EEWI

Drivers, Receivers, Transceivers Overview

The MAX213EEWI+ is a single-supply RS-232 transceiver from the MAX202E–MAX213E family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply (4.5V to 5.5V) and features four drivers and five receivers with full-duplex communication capability. The device supports data rates up to 120kbps and includes an integrated charge pump to generate ±10V internal rails without external bipolar supplies. It provides high ESD protection of ±15kV (HBM) and incorporates low-power shutdown modes, drawing typically 1μA in standard shutdown and 15μA for the MAX213E variant. The component is housed in a 28-pin SOIC package and is rated for operation over an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for external bipolar power supplies, enabling operation from a single +5V source.
• High electrostatic discharge protection ratings ensure robustness against ±15kV human body model discharges on all RS-232 I/O pins.
• Low-power shutdown mode significantly reduces current consumption while maintaining functionality for specific receiver channels.
• Two dedicated receivers remain active during shutdown to monitor external activity, supporting wake-up applications.

Drivers, Receivers, Transceivers Applications

• Battery-powered portable equipment requiring minimal standby current
• Hand-held diagnostic tools and measurement instruments
• Notebook computers and mobile devices with frequent serial port connections

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'EWI+' corresponds to the 28-pin SOIC package and the -40°C to +85°C industrial temperature grade. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the component matches the specific pinout and electrical characteristics defined in the MAX202E-MAX241E datasheet before integration into designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple transmitter and receiver channels within a single IC footprint. The MAX213E is distinct from similar family members due to its two awake-in-shutdown receivers and specific control pin polarities. Verify that the application does not exceed the maximum data rate of 120kbps under heavy capacitive loads. Consider the 28-pin package constraints for PCB layout compared to smaller package options available in the same product family.

Drivers, Receivers, Transceivers Part Context

The MAX213EEWI+ belongs to the Maxim Integrated MAX202E–MAX213E family of RS-232 transceivers. This series is characterized by its ability to operate from a single 5V supply using internal charge pumps. The 'E' designation indicates enhanced ESD protection capabilities compared to standard versions. The part is widely used in legacy serial communication interfaces where reliability and low power consumption are critical design parameters.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents within the same family include the MAX211EEWI+, which lacks the awake-in-shutdown receivers. Cross-manufacturer replacements such as the Texas Instruments MAX213CDW offer similar specifications but may differ in propagation delay and package availability. Always verify pin compatibility and electrical tolerances before substituting.
