MAX208CDWR

Drivers, Receivers, Transceivers Overview

The MAX208CDWR is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 5-V supply and includes four drivers and four receivers for full-duplex communication. The device features integrated charge pumps that generate the required positive and negative voltages for RS-232 signaling without external components. It provides ±15-kV electrostatic discharge (ESD) protection on all RS-232 lines, ensuring robustness in harsh environments. The component supports data rates up to 120 kb/s and is housed in a 24-pin SOIC package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' indicates the SOIC-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the exact temperature grade and packaging format required for the design. Cross-reference with the latest datasheet revision to confirm pinout and electrical characteristics remain unchanged.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a multichannel RS-232 solution with high ESD immunity is required. It is suitable for designs needing four independent transmit and receive channels. Consider the 120 kb/s speed limit for application compatibility. Evaluate the SOIC-24 package dimensions against available PCB space. Compare against newer generations like the TRS208 series if lower power consumption is a priority.

Drivers, Receivers, Transceivers Part Context

The MAX208 belongs to the broader family of RS-232 interface transceivers designed for serial communication. It serves as a bridge between TTL/CMOS logic levels and RS-232 voltage levels. The CDWR suffix denotes the commercial temperature range and tape-and-reel packaging. This part is widely used in legacy and modern industrial applications requiring robust serial connectivity.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS208IDWR is a direct functional replacement within the Texas Instruments portfolio. Both parts share identical pinouts and electrical specifications. Verify that the replacement part meets the same ESD protection and data rate requirements. Check for any minor differences in capacitor recommendations or operating current.
