ICL3224CA-T

Overview

The ICL3224CA-T is a full RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for serial communication applications. It integrates two drivers and two receivers within a single package, supporting data rates up to 500 kb/s. The device operates with a supply voltage range of 3V to 5.5V, ensuring compatibility with both 3.3V and 5V logic systems. It features ESD protection and functions within an operating temperature range of 0°C to +70°C. The component is housed in a 20-pin SSOP package, suitable for surface-mount installation.

Feature Summary

• Integrates dual drivers and dual receivers for complete RS-232 signal conversion
• Supports operation across standard 3.3V and 5V power supply voltages
• Includes electrostatic discharge (ESD) protection mechanisms
• Complies with EIA/TIA-232 and V.28/V.24 interface standards

Applications

• Serial port connections in industrial control systems
• Data communication interfaces in embedded devices
• Modem and peripheral interconnects requiring RS-232 signaling

Procurement Notes

Verify the specific suffix 'CA' against official Renesas documentation to confirm the commercial temperature grade and pinout configuration. Confirm RoHS compliance status as indicated in current datasheets. Check for obsolete status or active substitute recommendations from the manufacturer before procurement planning.

Selection Notes

Select this component when a compact solution for bidirectional RS-232 communication is required. Ensure the application environment stays within the specified 0°C to +70°C operational range. Verify that the system power supply aligns with the 3V to 5.5V input requirements. Consider the 20-lead SSOP footprint constraints during PCB layout design.

Part Context

This part belongs to the ICL3224 series of RS-232 transceivers from Renesas Electronics.
