ICL3221CVZ-T7

Overview

The ICL3221CVZ-T7 is an RS-232 transceiver manufactured by Renesas Electronics. It operates on a single 3V to 5.5V supply and supports data rates up to 500 kb/s. The device integrates three drivers and five receivers in a TSSOP-20 package. Key electrical parameters include a propagation delay of 0.3 ns, a maximum operating temperature of +70°C, and a minimum of 0°C. The quiescent current is specified at 10 uA. It complies with RoHS standards and utilizes reel packaging for surface mount installation.

Feature Summary

• Integrates multiple driver and receiver channels within a single compact package
• Supports full-duplex communication over RS-232 interfaces
• Features low power consumption with minimal quiescent current draw

Applications

• Industrial control systems requiring serial communication
• Portable battery-powered equipment utilizing low voltage operation
• Data acquisition modules interfacing with RS-232 peripherals

Procurement Notes

Verify the specific suffix T7 indicates reel packaging when sourcing. Confirm the component status as End of Life (EOL) with notifications extending through August 2026. Ensure compatibility with existing PCB footprints for TSSOP-20 packages during procurement planning.

Selection Notes

Select this component when three drivers and five receivers are required in a space-constrained design. Verify that the 500 kb/s data rate meets system timing requirements. Ensure the operating environment remains within the 0°C to +70°C commercial temperature range for reliable performance.

Part Context

This part belongs to the ICL3221 series of RS-232 transceivers. It shares core functionality with variants like ICL3221CVZ but differs in packaging and shipping configuration. The T7 suffix specifically denotes tape and reel delivery, distinguishing it from tube or cut tape options available in the same family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the ICL3221 series for pin-compatible alternatives if supply constraints persist.
