MAX208EEWG+

Drivers, Receivers, Transceivers Overview

The MAX208EEWG+ is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a +5V supply and features four drivers and four receivers, supporting full-duplex communication at data rates up to 120kbps. The device incorporates an integrated charge pump to generate the required ±10V internal voltages without external bipolar supplies. It provides high electrostatic discharge protection of ±15kV (Human Body Model) on all RS-232 inputs and outputs. The component is housed in a 24-pin SOIC package and functions within an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables operation from a single +5V power supply, eliminating the need for external dual-voltage sources.
• Robust ±15kV ESD protection on driver outputs and receiver inputs ensures reliability in harsh environments or frequent connection scenarios.
• Receiver inputs feature tight logic thresholds that maintain compatibility with TTL and CMOS logic levels while meeting RS-232 specifications.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power serial communication
• Hand-held diagnostic tools and portable instrumentation
• Notebook computers and mobile devices with frequent port connections

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EWG+' against the manufacturer's current datasheet to confirm the package type and RoHS compliance status. Ensure the ordering code matches the exact pinout and electrical characteristics required for the design. Cross-reference the manufacturer's official documentation for any recent lifecycle changes or obsolescence notices before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and high ESD immunity is critical for the application. The MAX208E variant specifically provides four drivers and four receivers, making it suitable for complex serial interfaces. Verify that the required data rate does not exceed 120kbps under the specific load capacitance conditions of the design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers designed for single-supply operation. The 'E' designation indicates enhanced ESD protection compared to standard versions. The 'W' suffix typically denotes the SOIC package format, while 'G+' signifies lead-free and RoHS-compliant manufacturing standards.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX208EAG+T serves as a direct alternative offering identical electrical performance in an SSOP-24 package. Designers must verify pin-to-pin compatibility and ensure the footprint accommodates the slight dimensional differences between the SOIC and SSOP packages.
