ICL3223CA-T

Overview

The ICL3223CA-T is a dual RS-232 transceiver manufactured by Renesas Electronics (formerly Intersil), designed for full-duplex communication. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device features two drivers and two receivers with a maximum data rate of 250 kb/s. It incorporates an automatic power-down mode that reduces operating supply current to approximately 1 µA when inputs are unconnected. The component provides 15 kV electrostatic discharge (ESD) protection on all pins and is housed in a 20-pin SSOP package suitable for surface-mount installation.

Feature Summary

• Automatic power-down mode activates when receiver inputs are left open or grounded, significantly reducing quiescent current consumption.
• Integrated 15 kV ESD protection on all RS-232 signal pins ensures robustness against electrostatic discharge events.
• Single 3 V to 5.5 V power supply operation simplifies system design by eliminating the need for external charge pumps or multiple voltage rails.

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems utilizing RS-232 serial communication
• Embedded devices interfacing with modems or peripheral instruments

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations such as CAZ or EIVZ indicate differences in temperature grade, packaging format, or lead finish. Confirm availability status, as specific variants may be discontinued or subject to limited stock constraints depending on the distributor region.

Selection Notes

Select this component for applications requiring dual-channel RS-232 connectivity with minimal power consumption during idle states. Ensure the chosen package variant matches the PCB footprint requirements and that the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the ICL3223 series of RS-232 transceivers from Renesas/Intersil. The series includes variants like ICL3223ECAZ and ICL3223EIVZ-T, which differ primarily in industrial temperature ratings and reel packaging options while maintaining identical electrical performance characteristics.
