MAX222IDW

Overview

The MAX222IDW is a dual RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex communication. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 200 kb/s. The device integrates two drivers and two receivers in an SOIC-Wide-18 package. It functions reliably across an extended temperature range from -40°C to +85°C with a typical operating supply current of 10 mA.

Feature Summary

• Integrates dual line drivers and receivers for full-duplex RS-232 communication
• Operates on a single 5-V power supply
• Includes internal charge pump circuitry to generate required voltages

Applications

• Industrial control systems requiring serial communication
• Portable battery-powered instruments
• Modems and fax machines

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and environmental compliance. Ensure the component meets RoHS standards if required for your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a dual-channel RS-232 interface is needed with low power consumption. It is suitable for applications requiring operation from a single 5-V source without external negative voltage supplies. Consider the SOIC-Wide-18 package dimensions during PCB layout planning.

Part Context

This device belongs to the MAX222 series of RS-232 transceivers. It provides a compact solution for serial communication interfaces in space-constrained designs. The series is known for integrating charge pumps to eliminate the need for external negative voltage generators.
