ICL3223IV

Overview

The ICL3223IV is a dual driver, dual receiver RS-232 transceiver manufactured by Renesas Electronics. It operates on a single 3V to 5.5V power supply and supports data rates up to 250 kb/s. The device features full-duplex communication with two drivers and two receivers. It includes 15 kV ESD protection on all pins and offers low power consumption with a typical operating current of 1 mA. The component is housed in a TSSOP-20 package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated 15 kV auto-downconverting ESD protection on all pins for enhanced robustness
• Single-supply operation compatible with 3V and 5V logic levels
• Low power architecture suitable for battery-powered applications

Applications

• Industrial equipment serial communication interfaces
• Portable devices requiring low-power RS-232 connectivity
• Office automation systems

Procurement Notes

Verify the specific suffix IV against official Renesas documentation to confirm the industrial temperature grade and TSSOP-20 packaging. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure compliance with RoHS directives if required for the target assembly process.

Selection Notes

Select this component when designing systems requiring reliable RS-232 communication in harsh environments due to its high ESD tolerance. It is appropriate for designs needing a single 3V to 5.5V supply rail without generating negative voltages internally. Consider the TSSOP-20 footprint constraints during PCB layout planning.

Part Context

This part belongs to the ICL3223 series of RS-232 interface ICs from Renesas (formerly Intersil). The series provides standard TIA/EIA-232-F compatibility. The IV suffix typically denotes the industrial temperature range variant packaged in TSSOP-20, distinguishing it from commercial or other package options within the same functional family.

Replacement Considerations

Check for direct pin-compatible alternatives such as the ICL3223ECAZ for SSOP-20 packaging or ISL3223 variants. Verify that substitute components maintain the 15 kV ESD protection level and 250 kb/s data rate specifications.
