ICL3224CAZ

Overview

The ICL3224CAZ is a single-driver, dual-receiver RS-232 transceiver manufactured by Renesas Electronics. It operates on a single 3 V to 5.5 V supply and supports data rates up to 500 kb/s. The device features low power consumption with a typical operating current of 10 µA and includes an automatic power-down mode that reduces standby current to less than 30 µA when inputs are idle. It provides ±15 kV ESD protection on all pins and utilizes internal charge pumps to generate required voltages without external components. The component is housed in a 20-pin SSOP package.

Feature Summary

• Integrates one driver and two receivers for full-duplex communication
• Supports operation from a single 3 V to 5.5 V power supply
• Includes automatic power-down mode for reduced standby current
• Provides ±15 kV ESD protection on all signal lines

Applications

• Industrial control systems requiring serial communication
• Portable battery-powered equipment due to low power consumption
• Modem interfaces and peripheral connections

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm temperature range and RoHS compliance status. Ensure the ordering code matches the exact pinout and package dimensions required for the design. Cross-reference with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when a single transmitter and two receivers are needed for RS-232 links. It is suitable for applications requiring low quiescent current and high ESD immunity. Compare against the ICL3221 for single-channel needs or the ICL3243 for higher channel counts. Verify voltage levels match the system's logic requirements.

Part Context

This part belongs to the ICL322x series of RS-232 transceivers from Renesas (formerly Intersil). It shares architectural similarities with other members like the ICL3221 but offers additional receiver channels. The series is designed for general-purpose serial communication in industrial and commercial environments.

Replacement Considerations

Direct substitutes include the ICL3221EIAZ for single-channel applications or the MAX3221EIAZ from Maxim Integrated. Verify pin compatibility and electrical specifications before substitution.
