ICL3222ECV

Overview

The ICL3222ECV is an RS-232 transceiver from the ICL3222 series manufactured by Renesas Electronics. It operates on a single power supply ranging from 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device features one driver and two receivers with a data rate of 500 kb/s. It includes a shutdown mode that reduces operating current to 1 mA. The component provides ±15 kV electrostatic discharge (ESD) protection on all RS-232 lines and meets EIA/TIA-232 specifications. It is housed in a TSSOP-20 package suitable for surface mount installation.

Feature Summary

• Integrated shutdown mode for low-power operation
• High ESD protection rating on communication lines
• Single-supply compatibility with standard voltage levels

Applications

• Portable equipment requiring RS-232 connectivity
• Battery-powered industrial control systems
• Modems and portable instruments

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm temperature range and packaging type. Ensure the source document explicitly identifies the part as ICL3222ECV to distinguish it from similar variants within the ICL3222 family. Confirm RoHS compliance status through official datasheets or environmental reports provided by Renesas.

Selection Notes

Select this component when a single-driver, dual-receiver RS-232 interface is required with low standby current capabilities. It is suitable for designs needing 500 kb/s transmission speeds within a 3 V to 5.5 V supply range. Consider the TSSOP-20 package constraints and thermal requirements for the target application environment.

Part Context

The ICL3222ECV belongs to the ICL3222 series of RS-232 transceivers designed for low-voltage applications. This series typically includes variants with different driver/receiver counts and temperature grades. The 'E' suffix generally denotes an extended commercial temperature range, while 'C' may indicate specific packaging or testing configurations depending on the manufacturer's naming convention.

Replacement Considerations

Check for direct substitutes like the ICL3222EIVZ or other ICL3222 series members with compatible pinouts and electrical characteristics. Verify if alternative RS-232 transceivers from other manufacturers meet the same 3 V to 5.5 V supply and 500 kb/s speed requirements without modifying the existing circuit design.
