MAX213ECWI

Drivers, Receivers, Transceivers Overview

The MAX213ECWI is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a +5V supply and includes four drivers and five receivers, supporting data rates up to 120kbps. The device features integrated charge-pump circuitry requiring only four external 0.1µF capacitors. It provides ±15kV ESD protection per the Human Body Model. The 'E' suffix indicates an extended temperature range of -40°C to +85°C, while the 'CW' suffix denotes a 28-pin SSOP package. Two receivers remain active during shutdown mode.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high ±15kV HBM ESD protection for robust operation in harsh environments
• On-board dc-to-dc converters enable single +5V supply operation without bipolar supplies
• Two receivers remain functional in shutdown mode to monitor external activity
• Low-power shutdown mode significantly reduces supply current consumption

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the component marking against the official datasheet pinout and electrical specifications. Confirm that the package matches the 28-pin SSOP form factor. Ensure the temperature grade corresponds to the industrial range requirements. Cross-reference the manufacturer part number with authorized distribution channels to confirm authenticity and traceability.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low power consumption alongside standard RS-232 connectivity. The inclusion of two awake-in-shutdown receivers makes it suitable for applications needing line monitoring during sleep states. Verify that the system voltage remains within the specified +4.5V to +5.5V range for optimal performance.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX202E–MAX213E family of RS-232 transceivers. It shares architectural similarities with the MAX211E but differs in control logic polarity and receiver behavior during shutdown. The MAX213E specifically allows two receivers to stay active while the rest enter a high-impedance state, distinguishing it from other members of the series.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers: MAX213EEWI+ (same function, different package).

Drivers, Receivers, Transceivers FAQ

How does the MAX213E handle shutdown mode differently from the MAX211E?

In shutdown mode, the MAX213E keeps receivers R4 and R5 active to monitor the line, whereas all receivers on the MAX211E are inactive.

What is the polarity of the Enable and Shutdown pins on the MAX213E?

The Enable pin is active high, and the Shutdown pin is active low, which is reversed compared to the MAX211E and MAX241E.

What external components are required for the charge pump?

Four external 0.1µF capacitors are required to support the internal charge-pump voltage converters.
