ICL3238CAZ

Overview

The ICL3238CAZ is a single RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in an SSOP-28 package. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device provides one driver and three receivers with a data rate capability of 500 kb/s. It features low power consumption with a typical operating current of 1 mA and includes 15 kV electrostatic discharge (ESD) protection on all pins. The component functions across a commercial temperature range from 0°C to +70°C.

Feature Summary

• Integrated ESD protection rated at 15 kV for robust signal integrity
• Low power operation suitable for battery-powered applications
• Single-driver and triple-receiver configuration for flexible interface design

Applications

• RS-232 serial communication interfaces
• Portable battery-operated equipment
• Modems and handheld terminals

Procurement Notes

Verify the End-of-Life status before procurement planning. Confirm that the SSOP-28 package dimensions match the target PCB footprint. Ensure compatibility with the required 3 V or 5 V supply rails and check if the 500 kb/s speed meets system requirements.

Selection Notes

Select this component when a single driver and multiple receivers are needed in a compact form factor. Consider the 0°C to +70°C operating range against environmental conditions. Verify that the 500 kb/s maximum data rate is sufficient for the application's throughput needs.

Part Context

This part belongs to the ICL3238 series of RS-232 transceivers. It is designed for low-voltage applications requiring minimal power consumption while maintaining standard RS-232 signal levels. The manufacturer indicates this specific part number is discontinued.

Replacement Considerations

Check for active equivalents from the same family or other manufacturers offering similar 3V/5V single-driver triple-receiver configurations in SSOP-28 packages.
