MAX222IDWRG4

Overview

The MAX222IDWRG4 is a dual RS-232 line driver and receiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating voltage of 5 V. The device supports full-duplex communication at data rates up to 200 kb/s. It features two drivers and two receivers, consuming 10 mA of supply current. The component functions reliably across an industrial temperature range from -40°C to +85°C. It includes ESD protection and is housed in an SOIC-Wide-18 surface-mount package.

Feature Summary

• Integrates dual independent drivers and receivers for simultaneous bidirectional serial communication
• Provides electrostatic discharge (ESD) protection capabilities
• Designed for single-supply operation using standard 5 V power rails

Applications

• Industrial control systems requiring RS-232 connectivity
• Point-of-sale terminals and barcode scanners
• Medical equipment with serial interface requirements

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm that the SOIC-Wide-18 package dimensions match the target PCB footprint design. Check for any product change notifications regarding manufacturing site transfers or material updates before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel RS-232 transceiver is required for 5 V systems. Ensure the application does not exceed the 200 kb/s maximum data rate specification. Verify that the available board space accommodates the wider SOIC package variant rather than the narrow version. Consider the 10 mA quiescent current consumption against total system power budgets.

Part Context

This part belongs to the MAX222 series of RS-232 transceivers from Texas Instruments. It serves as a specialized interface solution for converting TTL/CMOS logic levels to RS-232 voltages. The device is distinct from other MAX232 family members by its specific wide-package configuration and dual-driver architecture optimized for 5 V operation.

Replacement Considerations

The MAX232IDWR is a functional equivalent within the same family offering similar dual-driver capabilities. Verify pin compatibility and package width differences between the MAX222 and MAX232 variants during replacement evaluation.
