MAX3223CPW

Overview

The MAX3223CPW is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device integrates two drivers and two receivers, enabling full-duplex communication with data rates up to 500 kbit/s. It features ±15-kV electrostatic discharge (ESD) protection on the bus pins, meeting TIA/EIA-232-F and ITU v.28 standards. The component is housed in a 20-pin TSSOP package.

Feature Summary

• Integrated ESD protection for RS-232 bus pins
• Supports 3-V to 5.5-V supply operation
• Dual driver and dual receiver configuration

Applications

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

Procurement Notes

Verify the specific suffix 'CPW' against the manufacturer's official documentation to confirm the exact package type and temperature grade. Ensure compliance with RoHS directives if required for the target market. Cross-reference the datasheet revision date to validate current specifications before procurement.

Selection Notes

Select this component when a dual-channel RS-232 transceiver with high ESD immunity is required. It is suitable for applications needing operation across a wide voltage range from 3 V to 5.5 V. Consider the TSSOP-20 package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the MAX3223 family of multichannel RS-232 transceivers. It shares functional similarities with other devices in the series but differs in package and specific electrical characteristics. The CPW suffix typically denotes a specific tape-and-reel or tube packaging option within the TSSOP-20 form factor.

Replacement Considerations

Direct replacements include MAX3223EIPW and TRS3223CPWR. Verify pin compatibility and electrical parameters such as data rate and ESD protection levels before substitution.
