ICL3222ECAZ

Overview

The ICL3222ECAZ is a dual RS-232 transceiver manufactured by Renesas Electronics, designed for low-power applications. It operates on a single 3V to 5.5V supply and supports data rates up to 1Mbps. The device features two drivers and two receivers with full-duplex communication capability. It includes an automatic power-down mode that reduces supply current to less than 1µA when inputs are unconnected. The component offers 15kV ESD protection on RS-232 lines and operates within a temperature range of -40°C to +85°C. It is housed in a 20-pin SSOP package.

Feature Summary

• Integrates dual drivers and receivers for full-duplex RS-232 communication
• Features automatic power-down mode for ultra-low standby current consumption
• Provides robust 15kV human body model ESD protection on all RS-232 lines

Applications

• Portable battery-powered equipment requiring low power consumption
• Industrial control systems operating in harsh environments
• Modems and portable instruments with serial communication interfaces

Procurement Notes

Verify the specific suffix 'ECAZ' against official Renesas documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with the target PCB footprint for the SSOP-20 package. Confirm moisture sensitivity level requirements for the assembly process. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with strict power constraints. It is suitable for designs needing operation from a single 3V or 5V supply rail. Consider the 1Mbps data rate limit for high-speed serial applications. Evaluate the SSOP-20 package size against available board space constraints.

Part Context

This part belongs to the ICL3222 series of RS-232 transceivers. It shares functional similarities with other members like the ICL3222EIAZ but may differ in environmental rating or packaging details defined by the suffix. The series is known for combining low power consumption with high performance in a compact form factor.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX3222 or SP3222. Verify that substitute components support the same 3V to 5.5V supply range and 1Mbps data rate. Ensure equivalent ESD protection levels and package dimensions for mechanical fit.
