ICL3221ECV

Overview

The ICL3221ECV is a single-driver, single-receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s in full-duplex mode. The device integrates charge pumps for RS-232 voltage generation and provides 15 kV ESD protection on all pins. It is housed in a TSSOP-16 surface-mount package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors
• High electrostatic discharge (ESD) protection rated at 15 kV
• Low power consumption with 1 mA operating current

Applications

• RS-232 serial communication interfaces
• Modem connections
• Portable battery-powered instruments

Procurement Notes

Verify the specific suffix 'CV' against official Renesas documentation to confirm the exact tape-and-reel or tube packaging configuration. Ensure the component meets RoHS compliance requirements for the target region. Confirm moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a single-channel RS-232 interface is required with low power consumption. It is suitable for applications needing 15 kV ESD protection without external components. Verify that the 250 kb/s data rate meets system timing requirements.

Part Context

This part belongs to the ICL3221 series of RS-232 transceivers. It shares functional similarities with other single-driver devices in the Intersil/Renesas portfolio but is distinguished by its specific voltage range and ESD protection ratings.

Replacement Considerations

Check for direct pin-compatible substitutes such as the MAX3221 or SP3221. Verify that alternative components support the same 3 V to 5.5 V supply range and 250 kb/s data rate before substitution.
