MAX202IDW

Drivers, Receivers, Transceivers Overview

The MAX202IDW is a dual RS-232 line driver and receiver manufactured by Texas Instruments, designed for single-supply operation. It integrates two drivers and two receivers within a 16-pin SOIC package. The device operates on a single +5V supply, utilizing internal charge pumps to generate the required ±10V levels for RS-232 signaling. Key electrical parameters include a data rate of up to 120 kb/s, a supply voltage range of 4.5V to 5.5V, and an operating current of 15 mA. It supports full-duplex communication and features ±15 kV ESD protection on all pins.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge pumps to convert a single +5V supply into the ±10V output levels required for RS-232 communication without external high-voltage sources.
• Provides robust electrostatic discharge (ESD) protection rated at ±15 kV on all pins, including ground, ensuring signal integrity in harsh environments.
• Supports asynchronous serial communication with a maximum data signaling rate of 120 kbps while maintaining compliance with TIA/EIA-232-F standards.

Drivers, Receivers, Transceivers Applications

• Providing electrical interfaces between microcontrollers or asynchronous controllers and serial port connectors.
• Enabling serial communication in battery-powered systems where only a single +5V supply is available.
• Facilitating data exchange in industrial control systems requiring reliable RS-232 connectivity.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-16 package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering specifications match the required tape-and-reel or tube packaging options available for this part number.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX202IDW when a dual-channel RS-232 transceiver is needed with integrated charge pumps for single-supply applications. Compare against the MAX202IDR if reel packaging is preferred over tubes. Consider the TRS202E series if enhanced ESD protection beyond ±15 kV is required for specific interface standards.

Drivers, Receivers, Transceivers Part Context

The MAX202IDW belongs to the MAX202 family of RS-232 transceivers from Texas Instruments. This series is characterized by its ability to operate from a single 5V source, eliminating the need for negative voltage supplies typically associated with older RS-232 standards. It serves as a direct replacement for legacy components in modern embedded designs.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX202IDR is a functional equivalent offering identical electrical performance but supplied in tape-and-reel packaging instead of tubes. Verify pin compatibility and package dimensions before substitution to ensure board layout alignment.
