MAX202IDE4

Drivers, Receivers, Transceivers Overview

The MAX202IDE4 is a dual RS-232 transceiver manufactured by Texas Instruments, designed for asynchronous communication controllers. It integrates two line drivers and two line receivers with an internal charge pump circuit requiring only four small external capacitors for operation from a single 5V supply. The device supports data rates up to 120 kbps and provides ±9V output swings. It features ±15-kV ESD protection on all pins relative to ground, ensuring robust signal integrity. The component operates within a voltage range of 4.5V to 5.5V and is available in a 16-pin SOIC package suitable for surface mount applications.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual drivers and receivers with internal charge pump for single-supply operation
• Provides ±15-kV human body model ESD protection on all pins
• Supports full RS-232 protocol compliance for serial communication interfaces

Drivers, Receivers, Transceivers Applications

• Asynchronous communication between microcontrollers and serial connectors
• Industrial control systems requiring robust serial interface connectivity
• Embedded devices needing reliable RS-232 signal translation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per manufacturer documentation. Confirm the industrial temperature grade associated with the 'I' designation matches system requirements. Ensure ordering quantities align with standard reel or tube packaging specifications provided by authorized distributors. Cross-reference the exact part number against current datasheets to confirm pinout and electrical characteristics remain unchanged.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring isolated RS-232 signaling from a 5V logic domain. The integrated charge pump eliminates the need for negative voltage supplies, simplifying power architecture. Consider the 120 kbps speed limit for high-speed applications where faster transceivers might be necessary. Verify that the 16-pin SOIC footprint fits the PCB layout constraints and thermal management requirements of the target enclosure design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202 family of RS-232 transceivers, widely used for legacy serial port implementations. The 'ID' suffix typically denotes an industrial temperature range and SOIC package variant. The 'E4' suffix specifically identifies environmental compliance attributes, such as lead-free manufacturing processes, distinguishing it from older non-compliant versions while maintaining functional equivalence.

Drivers, Receivers, Transceivers Replacement Considerations

MAX202IDR serves as a direct functional substitute within the same product family. ADM202JRNZ-REEL from Analog Devices offers a compatible alternative for dual-channel RS-232 applications. Verify pin compatibility and electrical parameters before substituting to ensure seamless integration into existing designs.
