ICL3226CAZ-T

Overview

The ICL3226CAZ-T is a single-driver, single-receiver RS-232 transceiver manufactured by Renesas Electronics. It operates on a single power supply ranging from 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device achieves data rates up to 500 kb/s with a typical operating supply current of 1 mA. It features integrated ESD protection rated at 15 kV according to IEC 61000-4-2 standards. The component is housed in a 16-pin SSOP package and is designed for surface mount installation. It functions within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Integrated 15 kV ESD protection compliant with IEC 61000-4-2 standards for robust signal integrity.
• Single-supply operation capability supporting both 3.3 V and 5 V logic interfaces.
• Low power consumption design with a typical operating current of 1 mA.

Applications

• Portable battery-powered equipment requiring low power RS-232 communication.
• Industrial control systems utilizing serial data transmission.
• Embedded systems interfacing with modems or peripheral devices.

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus tube variants. Confirm RoHS compliance status through official datasheets as regulatory requirements evolve. Check for moisture sensitivity classification details prior to soldering. Ensure the supplier provides traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a single driver and receiver are sufficient for full-duplex communication. Consider the 500 kb/s speed limit against higher-speed alternatives if bandwidth requirements exceed this threshold. Evaluate the 15 kV ESD rating against environmental noise conditions. Verify that the SSOP-16 footprint matches the target PCB layout constraints.

Part Context

This part belongs to the ICL32xx series of RS-232 transceivers, originally developed by Intersil and now produced by Renesas. The series is known for compatibility with standard RS-232 protocols while offering improved power efficiency over older CMOS generations. The CAZ suffix typically denotes commercial grade temperature range and lead-free construction.

Replacement Considerations

Direct pin-compatible replacements within the same family include the ICL3221CAZ-T. For applications requiring different driver/receiver counts, consider the ICL3223CAZ-T (2 drivers/2 receivers) or ICL3227CAZ-T (2 drivers/2 receivers). Verify electrical parameters match before substitution.
