ICL3224CAZ-T

Overview

The ICL3224CAZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics, designed for single-supply operation at 3.0 V to 5.5 V. It integrates one driver and two receivers within a compact SSOP-20 surface-mount package. The device supports data rates up to 500 kb/s and operates reliably across an extended industrial temperature range from -40 °C to +85 °C. Key electrical characteristics include a maximum supply current of 1 mA and robust electrostatic discharge protection rated at 15 kV. This component facilitates full-duplex communication using single-ended signal types compliant with the RS-232 protocol.

Feature Summary

• Integrated power management features automatic shutdown mode to minimize energy consumption during idle periods.
• Built-in charge pump circuitry eliminates the requirement for external capacitors in standard configurations.
• High immunity to electrostatic discharge ensures reliable performance in electrically noisy environments.

Applications

• Industrial control systems requiring serial communication interfaces
• Portable battery-powered equipment needing low standby current
• Embedded systems utilizing RS-232 protocols for data transmission

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer designation aligns with Renesas Electronics or Intersil legacy branding. Ensure compliance with RoHS directives as specified in official documentation. Cross-reference the part number against current distributor catalogs to validate availability status and lead times prior to procurement planning.

Selection Notes

Select this model when a single driver and dual receiver configuration is required for RS-232 applications. Consider the SSOP-20 package dimensions for PCB layout constraints. Evaluate the 500 kb/s data rate capability against system timing requirements. Verify that the operating voltage range matches the target power supply infrastructure.

Part Context

This component belongs to the ICL3224 series of RS-232 interface integrated circuits. It represents a continuation of Intersil technology now managed under Renesas Electronics. The series is characterized by low power consumption and simplified external component requirements compared to earlier generations of line transceivers.

Replacement Considerations

Direct substitutes may include variants such as ICL3224EIAZ-T for extended temperature ranges. Verify pin compatibility and functional equivalence before swapping components. Consult official datasheets to confirm parameter alignment for critical design implementations.
