ICL3224IA-T

Overview

The ICL3224IA-T is a low-power RS-232 transceiver manufactured by Renesas Electronics, formerly Intersil. It integrates one driver and two receivers within an SSOP-20 package. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It supports data rates up to 500 kb/s and functions within a temperature range of -40°C to +85°C. The component includes ESD protection features and complies with RoHS standards. This specific part number indicates an industrial temperature grade variant.

Feature Summary

• Integrates one driver and two receivers for RS-232 communication
• Operates on a single 3 V to 5.5 V power supply
• Includes built-in ESD protection mechanisms
• Designed for low-power applications with 1 mA typical current consumption

Applications

• Portable battery-powered instruments requiring RS-232 connectivity
• Industrial control systems operating in moderate temperature environments
• Communication modules for embedded devices needing low power consumption

Procurement Notes

Verify the exact suffix against official Renesas documentation, as variations may indicate different packaging or temperature grades. Confirm availability status, as this component may be discontinued or subject to last-time buy notices. Ensure the SSOP-20 package matches your PCB footprint requirements. Check for moisture sensitivity level (MSL) ratings if reflow soldering is planned. Cross-reference the manufacturer date code to ensure component freshness and reliability.

Selection Notes

Select this component when a single-supply RS-232 interface is required with minimal power consumption. The 500 kb/s data rate suits standard asynchronous communication needs. Consider the SSOP-20 package size for space-constrained designs. Verify that the -40°C to +85°C operating range meets your environmental specifications. Compare against other ICL322x variants if additional drivers or receivers are needed.

Part Context

The ICL3224 belongs to the ICL322x family of RS-232 transceivers known for low power operation. These components are widely used in legacy serial communication interfaces. The 'IA' designation typically denotes industrial temperature range performance. The 'T' suffix often indicates tape and reel packaging for automated assembly. Renesas acquired Intersil, maintaining these product lines under their portfolio.

Replacement Considerations

Check for direct pin-compatible replacements within the ICL322x series, such as the ICL3221 or ICL3223, depending on driver/receiver count requirements. Verify electrical parameters like data rate and supply voltage compatibility. Ensure the replacement component supports the same SSOP-20 package. Confirm that any substitute maintains the required ESD protection levels and operating temperature range.
