MAX223EWI+T

Drivers, Receivers, Transceivers Overview

The MAX223EWI+T is a +5V-powered multichannel RS-232 transceiver featuring four drivers and five receivers. It operates within an extended temperature range of -40°C to +85°C and utilizes a 28-pin SO-Wide package. The device supports data rates up to 120 kb/s with a propagation delay of 40 µs. Operating from a single +5V supply, it draws 15 mA during active operation. The integrated charge pump eliminates the need for external bipolar supplies.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single-supply +5V operation without requiring external bipolar voltage sources.
• Includes internal capacitors to minimize printed circuit board space requirements.
• Features a shutdown mode that reduces power consumption to 5µW.

Drivers, Receivers, Transceivers Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 communication networks
• Portable diagnostic equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EWI+T' against official documentation to confirm the wide SOIC package, industrial temperature rating, and tape-and-reel packaging format. Ensure compatibility with existing PCB footprints and reflow profiles before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple transmit and receive channels on a single chip. It is suitable for applications where ±12V supplies are unavailable and board space is limited due to its integrated capacitor design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX220–MAX249 family of line drivers and receivers designed for EIA/TIA-232E and V.28/V.24 interfaces. The family offers various channel configurations and packages to accommodate different interface density and thermal requirements.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX223CWI+ is a compatible alternative within the same family. Note that the C-grade variant typically supports a commercial temperature range (0°C to +70°C), whereas the E-grade MAX223EWI+T supports the extended industrial range (-40°C to +85°C).
