MAX3237ECDBR

Overview

The MAX3237ECDBR is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 3-V to 5.5-V supply and supports data rates up to 1 Mb/s. The device integrates five drivers and three receivers, providing full-duplex communication capabilities. It features low power consumption with a typical operating supply current of 2 mA. The component includes shutdown functionality to minimize power usage during idle periods. It offers ±15-kV electrostatic discharge (ESD) protection on all lines according to human body model standards. The part is housed in a VSSOP-28 package.

Feature Summary

Procurement Notes

Verify the specific suffix 'DBR' indicates the tape-and-reel packaging format when ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the voltage range and channel count match system requirements before procurement.

Selection Notes

Select this component for applications requiring multiple RS-232 channels within a compact footprint. Compare against similar parts like the MAX3238 if extended temperature ranges are needed. Verify that the VSSOP-28 package fits the PCB layout constraints. Check compatibility with existing decoupling capacitor values specified in the datasheet.

Part Context

This part belongs to the MAX3237E family of multichannel RS-232 transceivers. It shares functional similarities with other members of the series but differs in package type and reel configuration. The ECDBR variant specifically denotes the VSSOP-28 package with tape-and-reel delivery, distinguishing it from tube-packaged equivalents.

Replacement Considerations

Direct substitutes include other MAX3237 variants with different packages such as MAX3237ECDW. Cross-reference pinouts and electrical characteristics carefully. Ensure thermal performance matches the new package type.
