ICL3226ECA-T

Overview

The ICL3226ECA-T is a single-driver, single-receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates on a single power supply ranging from 3V to 5.5V and supports data rates up to 250kbps. The device features enhanced automatic powerdown functionality, reducing supply current to 1mA in active mode and 1μA in shutdown. It includes ±15kV ESD protection per the human body model and utilizes an SSOP-16 surface-mount package. The component complies with EIA/TIA-232 and V.28/V.24 specifications.

Feature Summary

• Enhanced automatic powerdown mechanism for significant energy conservation
• Integrated charge pump requiring only four external capacitors
• Robust electrostatic discharge protection rated at ±15kV
• Receiver input hysteresis to improve noise immunity

Applications

• Battery-powered portable equipment and handheld devices
• Laptop computers and notebook systems
• Modems, printers, and peripheral interfaces
• Digital cameras and cellular/mobile phones

Procurement Notes

Verify the specific suffix 'ECA' against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Packaging variations such as cut tape or reel may affect handling procedures. Ensure the source provides valid RoHS compliance certificates and traceability records for quality assurance purposes.

Selection Notes

Select this component when designing low-power RS-232 links requiring minimal external capacitance. The 250kbps rate suits standard asynchronous communication needs. Verify that the system voltage remains within the 3V to 5.5V range. Consider the SSOP-16 footprint constraints during PCB layout planning.

Part Context

This part belongs to the ICL322x series of low-power RS-232 transceivers. It serves as a drop-in replacement for legacy components like the MAX3226 and MAX3238. The series is characterized by its ability to operate efficiently from a single 3V or 5V supply while maintaining full RS-232 signal levels.

Replacement Considerations

Publicly confirmed substitutes include ICL3226EIAZ-T and ICL3226IAZ. These variants share identical functional specifications but differ in packaging types, specifically tube versus cut tape configurations.
