MAX207CDW

Drivers, Receivers, Transceivers Overview

The MAX207CDW is a low-power RS-232 transceiver manufactured by Texas Instruments, designed for multi-line communication applications. It integrates five drivers and three receivers within a single package, supporting full-duplex data transmission at rates up to 120 kb/s. The device operates from a single 5 V supply with a typical operating current of 20 mA. Electrical specifications include a maximum power supply voltage of 5.5 V and a minimum of 4.5 V. The component features an output current capability of 10 mA and a propagation delay of 2 µs. It is housed in a 24-pin SOIC package and supports operation across an industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates five independent drivers and three receivers for comprehensive multi-line RS-232 connectivity.
• Supports full-duplex communication protocols with standard RS-232 signal levels.
• Operates efficiently on a single 5 V power supply without requiring negative voltage generation.

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring robust serial communication interfaces.
• Modem connections and peripheral interfacing in embedded devices.
• Data acquisition systems utilizing multiple RS-232 lines.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-24 package and commercial/industrial temperature grade during sourcing. Ensure compatibility with 5 V logic levels and confirm that the absence of a shutdown pin aligns with the system design requirements. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision status before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a design requires five transmit and three receive channels within a single IC footprint. It is suitable for applications needing moderate data rates up to 120 kb/s without the complexity of external charge pumps. Consider the SOIC-24 package constraints and thermal performance for the intended operating environment compared to alternatives like the MAX208 which offers different driver/receiver counts.

Drivers, Receivers, Transceivers Part Context

The MAX207 belongs to the MAX207 family of RS-232 transceivers, characterized by their ability to drive standard RS-232 voltages from a single 5 V supply. This series is widely used in legacy and modern industrial equipment where reliable serial communication is essential. The CDW variant specifically denotes the plastic small-outline integrated circuit package suitable for surface-mount assembly processes.
