MAX208IDBR

Drivers, Receivers, Transceivers Overview

The MAX208IDBR is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates with a single 5-V power supply and supports data rates up to 120 kb/s. The device integrates four drivers and four receivers, providing full-duplex communication capabilities. It features ±15-kV electrostatic discharge (ESD) protection on all RS-232 lines, ensuring robustness against ESD events per IEC 61000-4-2 standards. The component is housed in a 24-pin SSOP package and is rated for an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±15-kV ESD protection on all RS-232 transceiver lines
• Single 5-V power supply operation with internal charge pumps
• Four independent drivers and four independent receivers for full-duplex communication

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable serial communication
• Data acquisition equipment interfaces
• Point-of-sale terminals and barcode scanners

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IDBR' to confirm the industrial temperature grade (-40°C to +85°C) and the tape-and-reel packaging format. Ensure compatibility with the 24-SSOP footprint during PCB layout. Cross-reference the manufacturer's latest datasheet for any pinout revisions or RoHS compliance updates before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require high ESD immunity without external protection diodes. It is suitable for applications needing multiple RS-232 channels within a compact surface-mount footprint. Consider the 120 kb/s speed limit; higher-speed requirements may necessitate alternative interface solutions from the same family.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX208 series of multichannel RS-232 transceivers. It serves as a direct replacement for legacy MAX208 devices, offering improved ESD performance while maintaining functional compatibility. The IDBR variant specifically denotes the industrial temperature range and reel packaging, distinguishing it from commercial grade or tube-packaged versions.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS208IDBR is a recommended manufacturer replacement. Verify pin-to-pin compatibility and ensure the replacement part meets the same industrial temperature and ESD protection specifications.
