ICL3221CAZ-T

Overview

The ICL3221CAZ-T is a single-driver, single-receiver RS-232 transceiver from the ICL32xxE series by Renesas Electronics. It operates on a single power supply ranging from 3V to 5.5V and features automatic power-down mode for low standby current. The device supports data rates up to 500 kb/s with propagation delays of 0.15μs. It includes ESD protection rated at 15 kV according to IEC61000-4-2. Packaged in a 16-pin SSOP, it complies with V.28/V.24, EIA/TIA-232, and RoHS standards.

Feature Summary

• Automatic power-down mode reduces standby current consumption significantly when the receiver is idle.
• Integrated ESD protection meets IEC61000-4-2 standards for robust signal integrity.
• CMOS technology enables operation with a single 3V to 5.5V supply voltage.

Applications

• RS-232 serial communication interfaces
• Modem connections
• Portable battery-powered instruments

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm package type and temperature range. Ensure compatibility with ECAD tools using provided models. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Selection Notes

Select this component for applications requiring low-power RS-232 connectivity with automatic shutdown capabilities. Verify that the 16-pin SSOP package fits the PCB layout constraints. Check if the 500 kb/s data rate meets system requirements compared to higher-speed alternatives.

Part Context

Part of the ICL32xxE family, designed for low-voltage RS-232 applications. The CAZ suffix typically denotes the SSOP package variant. This series bridges legacy RS-232 standards with modern low-voltage CMOS logic families.

Replacement Considerations

Check datasheets for ICL3221EIAZ-T or ICL3221CVZ-T for pin-compatible alternatives in different packages like TSSOP. Verify electrical parameters match before substitution.
