ICL3224CA

Overview

The ICL3224CA is a single driver and dual receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates on a single power supply ranging from 3V to 5.5V, supporting data rates up to 120kbps. The device features enhanced automatic powerdown functionality that reduces supply current to less than 1µA when the receivers are idle. It includes ESD protection exceeding ±15kV according to the Human Body Model. The component is housed in a 16-SOIC package and is designed for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated automatic powerdown circuitry significantly lowers standby current consumption during periods of inactivity.
• Provides robust electrostatic discharge protection rated at ±15kV via the human body model method.
• Supports standard RS-232 voltage levels while functioning with a single low-voltage power supply.

Applications

• Portable battery-powered equipment requiring minimal standby power consumption
• Industrial control systems utilizing RS-232 communication protocols
• Embedded systems needing reliable serial data transmission with high noise immunity

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding pin configurations. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require reduced power consumption during idle states. It is suitable for applications where space constraints favor surface-mount packages. Consider the 120kbps speed limit when evaluating higher-speed interface requirements.

Part Context

This part belongs to the ICL322x series of RS-232 transceivers known for low-power operation. It serves as a bridge between microprocessor logic levels and RS-232 signal standards. The series is widely used in legacy and modern embedded designs requiring reliable serial connectivity.

Replacement Considerations

Check for ICL3224CAZ or similar variants for lead-free specifications. Verify pinout compatibility with direct replacements like MAX3224 if sourcing from alternative manufacturers.
