ICL3226EIAZ-T

Overview

The ICL3226EIAZ-T is a single-driver, single-receiver RS-232 line transceiver from the ICL32xxE series by Renesas Electronics. It operates on a single 3V to 5.5V supply and supports full-duplex communication at data rates up to 250 kb/s. The device features 15 kV ESD protection on all pins and meets EIA/TIA-232 standards. Packaged in a 16-pin SSOP with dimensions of 10.6mm x 2mm, it functions within a temperature range of -40°C to 125°C. Key electrical parameters include a maximum propagation delay of 0.15μs @ CL, a maximum high-level output current of 1.0mA, and a maximum low-level output current of 1.6mA.

Feature Summary

• Integrated 15 kV ESD protection on all pins for enhanced robustness
• Single-supply operation compatible with 3V and 5V logic levels
• Compliance with EIA/TIA-232 and V.28/V.24 interface standards

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered devices utilizing low-voltage operation
• Embedded systems interfacing with PC serial ports or modems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SSOP-16 footprint matches the target PCB layout constraints. Validate that the operating temperature range aligns with the final application environment requirements.

Selection Notes

Select this component for applications requiring a single driver and receiver with high ESD tolerance. Compare against the ICL3225EIAZ-T if dual drivers are needed instead of a single configuration. Consider the 250 kb/s data rate limit when designing for higher-speed serial links. Verify power consumption specifications against system battery life targets.

Part Context

This part belongs to the ICL32xxE family of CMOS RS-232 transceivers designed for low-power applications. It succeeds earlier Intersil designs under the Renesas Electronics portfolio. The device maintains compatibility with standard RS-232 signaling while offering improved electrostatic discharge immunity compared to legacy counterparts.

Replacement Considerations

The ICL3225EIAZ-T serves as a functional alternative for designs requiring two drivers and receivers. Other members of the ICL32xxE series may be considered based on pin count and driver/receiver configuration needs.
