ICL3224IA

Overview

The ICL3224IA is a dual RS-232 transceiver manufactured by Intersil, designed for operation with supply voltages ranging from 3 V to 5.5 V. It integrates two drivers and two receivers within an SSOP-20 package, supporting data rates up to 500 kb/s. The device operates at a typical supply current of 1 mA and functions across an industrial temperature range of -40°C to +85°C. It includes built-in ESD protection and utilizes enhanced automatic powerdown technology to minimize standby power consumption.

Feature Summary

• Integrates two independent drivers and two receivers for full-duplex communication
• Supports single-ended signal reception compliant with RS-232 standards
• Features enhanced automatic powerdown circuitry to reduce active and standby currents

Applications

• Industrial equipment requiring reliable serial communication interfaces
• Portable devices utilizing 3V or 5V logic systems
• Embedded systems needing low-power RS-232 connectivity

Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different packaging or environmental ratings. Confirm availability status through authorized channels, noting that older component lines may have limited stock or discontinuation notices. Ensure compliance with RoHS directives if required for the target assembly process.

Selection Notes

Select this component when a dual-channel RS-232 interface is required in a compact surface-mount form factor. It is suitable for designs operating between 3V and 5.5V where moderate data speeds are sufficient. Consider the SSOP-20 footprint during PCB layout planning to ensure adequate clearance for external capacitors.

Part Context

This part belongs to the ICL3224 series of RS-232 transceivers produced by Intersil, now part of Renesas Electronics. The series focuses on providing robust serial communication capabilities for applications demanding low power consumption and high noise immunity in small packages.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as variants with different temperature ranges or packaging options. Verify electrical specifications match exactly before substitution.
