ICL3223ECAZ

Overview

The ICL3223ECAZ is a dual driver, dual receiver RS-232 transceiver manufactured by Renesas Electronics. It operates from a single 3V to 5.5V power supply and supports data rates up to 250 kb/s. The device features 15 kV ESD protection on all RS-232 lines and includes automatic power-down functionality. It is housed in a 20-pin SSOP package with surface mount installation. Operating temperatures range from 0°C to +70°C, with a typical supply current of 1 mA.

Feature Summary

• Integrated automatic power-down circuitry reduces standby power consumption when no valid signal is present.
• Provides enhanced electrostatic discharge protection rated at 15 kV for robust communication reliability.
• Supports full-duplex data transmission compliant with standard RS-232 interface specifications.

Applications

• Industrial control systems requiring reliable serial communication interfaces
• Portable battery-powered equipment utilizing low-voltage operation
• Embedded systems needing compact surface-mount RS-232 connectivity

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance details and moisture sensitivity levels prior to procurement. Ensure storage conditions meet humidity requirements to prevent package degradation during handling and assembly processes.

Selection Notes

Select this component for applications requiring dual-channel RS-232 communication within a 3V to 5.5V voltage range. Consider the 250 kb/s data rate limit and SSOP-20 package constraints. Evaluate thermal performance within the 0°C to +70°C operating range against system environmental requirements.

Part Context

This part belongs to the ICL3223 series of RS-232 transceivers designed for low-power applications. It represents an evolution of Intersil's legacy interface solutions now managed by Renesas Electronics. The device integrates charge pump circuitry internally to generate required RS-232 voltage levels without external components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent models such as the ICL3223EIAZ or other series variants only if official datasheets confirm pin-to-pin equivalence and electrical parameter alignment.
