ICL3238IA-T

Overview

The ICL3238IA-T is a triple line transceiver manufactured by Renesas Electronics Corporation, designed for RS-232 communication applications. It integrates five drivers and three receivers within a single SSOP-28 package. The device operates on a single 3V to 5.5V power supply and supports data rates up to 250 kb/s. Key electrical specifications include a maximum operating temperature of 70°C and a minimum of -40°C. The typical operating supply current is 1 mA. It complies with EIA/TIA-232 standards and features Schmitt trigger inputs for noise immunity.

Feature Summary

• Integrates five drivers and three receivers in a compact SSOP-28 package
• Operates from a single 3V to 5.5V power supply
• Supports full-duplex communication at data rates up to 250 kb/s
• Features Schmitt trigger inputs for enhanced noise immunity

Applications

• RS-232 serial communication interfaces
• Industrial control systems requiring reliable data transmission
• Portable battery-powered devices due to low power consumption

Procurement Notes

Verify the manufacturer marking and date code against official Renesas documentation to ensure authenticity. Confirm that the SSOP-28 package matches the required footprint and pitch specifications for your PCB design. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range meets your specific application requirements.

Selection Notes

Select this component when a triple receiver configuration is needed alongside multiple driver outputs in a space-constrained design. Consider the 250 kb/s data rate limit for high-speed applications where faster alternatives may be necessary. Evaluate the single-supply operation capability if negative voltage generation is not available in the system design. Compare pin compatibility with existing designs if replacing legacy components.

Part Context

The ICL3238 series belongs to Renesas' portfolio of RS-232 interface solutions, evolving from Intersil's original designs. This specific part number indicates an industrial temperature grade variant packaged in SSOP-28. The suffix 'T' typically denotes tape and reel packaging for automated assembly processes. It serves as a bridge between microcontroller logic levels and standard RS-232 signal voltages.

Replacement Considerations

Check for direct pin-compatible replacements such as the ICL3238EIAZ or other variants within the same family. Verify that any substitute maintains the same driver/receiver count and voltage specifications. Ensure thermal performance characteristics align with your system's heat dissipation capabilities.
