MAX3223IPW

Overview

The MAX3223IPW is a dual-channel RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex data communication. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kb/s. The device integrates two drivers and two receivers in a single package. It features low power consumption with a typical operating supply current of 1 mA. The component is housed in a TSSOP-20 surface-mount package and is rated for an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates dual independent drivers and receivers for simultaneous bidirectional communication
• Operates directly from a single 3 V to 5.5 V power supply without external charge pumps
• Includes internal capacitors to minimize external component count and board space
• Provides ESD protection exceeding standard requirements for robust signal integrity

Applications

• Industrial control systems requiring serial communication interfaces
• Portable battery-powered equipment utilizing RS-232 connectivity
• Modems and fax machines implementing standard serial protocols
• Point-of-sale terminals and medical instrumentation

Procurement Notes

Verify the specific suffix IPW confirms the TSSOP-20 package and industrial temperature grade. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the source provides valid traceability for quality assurance purposes before finalizing procurement orders.

Selection Notes

Select this component when dual-channel RS-232 communication is required within a 3 V to 5.5 V system. It is suitable for designs prioritizing low power consumption and minimal external capacitance. Compare against similar models like the MAX3222EIPW if only single-channel functionality is needed. Verify that the TSSOP-20 footprint aligns with the target PCB layout constraints.

Part Context

This part belongs to the MAX3223 family of RS-232 transceivers from Texas Instruments. It serves as a direct replacement for legacy components requiring dual-channel serial interface capabilities. The IPW suffix specifically denotes the plastic small-outline thin-profile package variant. This series is widely used in embedded systems needing reliable serial data transmission.

Replacement Considerations

The MAX3223EIPWR is a reel-packaged alternative within the same functional family. The TRS3223IPWRG4 offers equivalent electrical specifications with different packaging options. Verify pin compatibility and thermal characteristics when substituting these parts.
