ICL3226IAZ-T

Overview

The ICL3226IAZ-T is an RS-232 transceiver manufactured by Renesas Electronics Corporation, formerly Intersil. It operates on a single 3V to 5.5V power supply and supports data rates up to 120 kbps. The device integrates one driver and one receiver, featuring automatic power-down mode that reduces supply current to less than 1 µA when inputs are unconnected or grounded. It complies with EIA/TIA-232 standards and includes ESD protection exceeding ±15 kV according to the Human Body Model. The component is housed in a 16-pin SSOP package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates automatic power-down functionality to minimize power consumption during idle states
• Provides robust electrostatic discharge protection on all pins without external components
• Supports standard RS-232 voltage levels with single-supply operation

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems utilizing serial communication interfaces
• Modems and other telecommunications devices adhering to EIA/TIA-232 specifications

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Selection Notes

Select this component when a single driver and receiver pair is sufficient for the application. Consider the automatic power-down feature for battery-operated devices where quiescent current is critical. Verify that the 120 kbps data rate meets the system requirements. Ensure the SSOP package dimensions fit the available PCB space constraints.

Part Context

This part belongs to the ICL322x series of low-power RS-232 transceivers from Renesas/Intersil. The series is designed for applications requiring minimal power consumption while maintaining compatibility with standard RS-232 protocols. The ICL3226 variant specifically offers a 1-driver/1-receiver configuration, distinguishing it from higher-channel counterparts like the ICL3232.
