ICL3238CA-T

Overview

The ICL3238CA-T is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, formerly Intersil. It integrates one driver and three receivers within a single SSOP-28 package. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It supports data rates up to 500 kb/s and features 15 kV electrostatic discharge (ESD) protection on all pins. The component is designed for surface-mount installation and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates one driver and three receivers in a compact SSOP-28 package
• Provides 15 kV ESD protection on all signal pins
• Operates on a single 3 V to 5.5 V power supply
• Supports data transmission rates up to 500 kb/s

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly. Confirm RoHS compliance status through official documentation. Check end-of-life status as previous listings indicated discontinuation. Ensure moisture sensitivity level requirements are met during storage and handling.

Selection Notes

Select this component when a single-driver, triple-receiver configuration is needed for RS-232 links. Consider the 500 kb/s speed limit for high-speed applications. Verify voltage compatibility with 3 V or 5 V systems. Evaluate the SSOP-28 footprint against available PCB space constraints.

Part Context

This part belongs to the ICL3238 series of RS-232 transceivers. It shares functional similarities with other Intersil/Renesas low-power serial interface chips. The CA variant denotes commercial temperature range operation. The suffix typically specifies reel packaging for manufacturing efficiency.

Replacement Considerations

Check for direct pin-compatible substitutes within the Renesas RS-232 portfolio. Verify electrical parameters match original design requirements. Consider newer generations with extended temperature ranges if environmental conditions change.
