MAX3223ECDW

Overview

The MAX3223ECDW is a dual-channel RS-232 transceiver manufactured by Texas Instruments, housed in a 20-pin SSOP package. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kbit/s. The device integrates two drivers and two receivers for full-duplex communication. Key electrical specifications include a maximum operating temperature of +70°C and a minimum of 0°C. It features ±15-kV ESD protection on RS-232 bus pins and meets TIA/EIA-232-F standards.

Feature Summary

• Integrated ±15-kV ESD protection on RS-232 bus pins for enhanced signal integrity
• Supports data transmission rates up to 500 kbit/s
• Operates with a single 3-V to 5.5-V power supply

Applications

• Industrial control systems requiring robust serial communication
• Portable battery-powered devices utilizing low-voltage operation
• Modems and facsimile machines adhering to RS-232 standards

Procurement Notes

Verify the specific suffix 'ECDW' against current manufacturer documentation to confirm availability status, as component lifecycles change frequently. Ensure the industrial or commercial temperature grade aligns with system requirements. Cross-reference the 20-SSOP package dimensions with PCB footprint libraries before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require dual RS-232 channels with integrated ESD protection. Verify that the 0°C to +70°C operating temperature range satisfies environmental constraints. Confirm compatibility with 3-V or 5-V logic levels and ensure the SSOP-20 package fits the available board space.

Part Context

This part belongs to the MAX3223E family of multichannel RS-232 line drivers and receivers. It shares functional similarities with other members like the MAX3223IDBR but differs in packaging and temperature rating. The ECDW variant specifically denotes the SSOP-20 package with commercial temperature limits.

Replacement Considerations

MAX3223EIDBR offers identical functionality in an SSOP-20 package but extends the operating temperature range to -40°C to +85°C. TRS3223ECPWG4 provides similar performance in a TSSOP-20 package. Verify pinout compatibility and thermal requirements before substituting.
