MAX208CDW

Drivers, Receivers, Transceivers Overview

The MAX208CDW is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 4.5 V to 5.5 V power supply and supports full-duplex communication with four drivers and four receivers. The device achieves data rates up to 120 kb/s and includes ±15 kV electrostatic discharge (ESD) protection on all inputs and outputs. It functions within an industrial temperature range of -40°C to +85°C, draws 20 mA of supply current, and is housed in a 24-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ESD protection rated at ±15 kV for robust signal integrity
• Single-supply operation simplifies power design requirements
• Full-duplex capability with four independent driver and receiver channels

Drivers, Receivers, Transceivers Applications

• Industrial serial communication systems requiring RS-232 interfaces
• Embedded devices needing reliable data transmission in noisy environments
• Equipment utilizing multiple serial ports for control and monitoring

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CDW indicates the SOIC-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the component meets the required operating temperature range for your specific application environment before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component when four independent RS-232 channels are necessary within a single integrated circuit. The wide operating temperature range makes it suitable for harsh industrial conditions compared to commercial-grade alternatives. Verify that the 120 kb/s data rate aligns with system timing requirements and that the SOIC-24 footprint fits the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX208 family of multichannel RS-232 transceivers designed for low-power applications. It serves as a bridge between microprocessors and serial communication lines. The device integrates charge pumps to generate the necessary voltage levels for RS-232 signaling without requiring external dual supplies.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS208IDBR is a recommended replacement from Texas Instruments. Verify pin compatibility and electrical specifications before substitution.
