ICL3226ECAZ

Overview

The ICL3226ECAZ is a single driver, single receiver RS-232 transceiver manufactured by Renesas/Intersil. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features enhanced automatic powerdown functionality, reducing operating supply current to 1 mA. It provides 15 kV electrostatic discharge (ESD) protection on all RS-232 lines. Packaged in an SSOP-16 format for surface mount installation, it functions as a full-duplex transceiver compliant with EIA/TIA-232 standards.

Feature Summary

• Enhanced automatic powerdown mechanism reduces standby current consumption significantly when the interface is idle.
• Integrated charge pump circuitry requires only four small external capacitors for voltage conversion.
• High noise immunity provided by receiver hysteresis characteristics.
• Robust protection against electrostatic discharge events on communication lines.

Applications

• Battery-powered handheld and portable equipment requiring low power consumption.
• Laptop computers and notebook systems needing compact serial interfaces.
• Modems, printers, and peripheral devices utilizing RS-232 connectivity.
• Digital cameras and cellular/mobile phones with serial communication ports.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinuation status. Confirm RoHS compliance documentation matches specific manufacturing lots. Check for moisture sensitivity level handling requirements during storage and assembly processes to ensure reliability.

Selection Notes

Select this component for designs requiring a single channel RS-232 interface with minimal quiescent current. Ensure the application environment stays within the commercial temperature range of 0°C to +70°C. Verify that the SSOP-16 package footprint aligns with the PCB layout constraints and that external capacitor values meet the datasheet specifications for stable operation.

Part Context

This part belongs to the ICL3226 series of low-power RS-232 transceivers. It serves as a drop-in replacement for legacy components like the MAX3226. The series is characterized by its ability to operate from a single 3V to 5.5V supply while maintaining compatibility with standard RS-232 voltage levels.

Replacement Considerations

Publicly confirmed substitute part numbers include MAX3226EIDR and MAX3226ECI. Verify pinout compatibility and electrical parameters before substitution. Note that some equivalents may differ in package type or temperature rating.
