ICL3224IAZ

Overview

The ICL3224IAZ is an RS-232 transceiver manufactured by Renesas Electronics Corporation, belonging to the ICL3224 series. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kb/s. The device integrates one driver and two receivers in a single-ended configuration. It is housed in an SSOP-20 surface-mount package and functions reliably across an industrial temperature range from -40 °C to +85 °C. The component draws a typical operating supply current of 1 mA and includes built-in ESD protection mechanisms.

Feature Summary

• Provides full-duplex communication capabilities for RS-232 serial interfaces
• Integrates internal charge pump circuitry to generate required voltage levels without external transformers
• Includes electrostatic discharge protection on input and output pins

Applications

• Industrial equipment requiring reliable serial communication links
• Portable computing devices utilizing low-voltage power supplies
• Embedded systems interfacing with legacy RS-232 peripherals

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Check for specific annealing suffixes if required by design specifications. Ensure storage conditions adhere to humidity sensitivity guidelines to prevent package damage during assembly processes.

Selection Notes

Select this component when a single driver and dual receiver configuration is necessary for RS-232 applications. It is suitable for designs requiring operation between 3 V and 5.5 V supply rails. Consider the SSOP-20 package dimensions for PCB layout constraints. Verify that the 500 kb/s data rate meets system timing requirements compared to lower-speed alternatives.

Part Context

This part belongs to the ICL3224 family of RS-232 interface integrated circuits produced by Renesas Electronics Corporation under the former Intersil brand. The ICL3224 series is designed for low-power applications requiring compatibility with standard RS-232 protocols. Related variants may offer different driver/receiver counts or enhanced ESD ratings within the same product line.

Replacement Considerations

The ICL3224EIAZ is a verified substitute offering similar functionality with specified 15 kV ESD protection. Both parts share the SSOP-20 package and core electrical characteristics. Verify pinout compatibility and ensure the replacement meets the specific ESD requirements of the target application environment.
