ICL3223IA-T

Overview

The ICL3223IA-T is a low-power RS-232 transceiver manufactured by Renesas Electronics under the Intersil brand. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device features one driver and two receivers with a data rate capability of 500 kb/s. It utilizes an SSOP-20 surface-mount package and draws only 1 mA of operating current. The component supports full-duplex communication and includes ESD protection mechanisms. It functions reliably across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Integrated single-ended receiver inputs for standard RS-232 signal compatibility
• Low power consumption design suitable for battery-operated applications
• Built-in electrostatic discharge protection for enhanced reliability

Applications

• Industrial control systems requiring serial communication
• Portable instrumentation and measurement devices
• Embedded systems with limited power budgets

Procurement Notes

Verify the suffix 'T' indicates reel packaging when sourcing. Confirm the manufacturer designation as Renesas Electronics or Intersil on the datasheet. Ensure the SSOP-20 package matches the footprint requirements. Check moisture sensitivity levels for proper storage handling before assembly.

Selection Notes

Select this component when a single driver and dual receiver configuration is required for RS-232 links. It is appropriate for designs needing 500 kb/s throughput at 3 V or 5 V supplies. Consider the SSOP-20 package constraints for PCB layout. Verify thermal performance within the specified -40 °C to +85 °C operational window.

Part Context

This part belongs to the ICL3223 series of RS-232 interface integrated circuits. It shares functional similarities with other members like the ICL3223ECAZ but differs in specific electrical characteristics and packaging options. The series is designed for general-purpose serial communication interfaces in commercial and industrial environments.
