ICL3238EIAZ-T

Overview

The ICL3238EIAZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics, operating within a 3 V to 5.5 V supply range. It integrates five drivers and three receivers in a single full-duplex package, supporting data rates up to 250 kb/s. The device features an active current consumption of 1 mA and includes power-down mode functionality for reduced standby usage. It provides 15 kV electrostatic discharge protection on all RS-232 lines and operates reliably across an industrial temperature range from -40 °C to +85 °C. The component is housed in a compact SSOP-28 surface-mount package.

Feature Summary

• Integrates five independent drivers and three receivers for comprehensive multi-port communication capabilities
• Features 15 kV ESD protection on all RS-232 lines to enhance signal integrity and device reliability
• Includes power-down mode that significantly reduces quiescent current consumption during idle periods

Applications

• Industrial control systems requiring robust serial communication interfaces
• Portable battery-powered equipment utilizing low-voltage logic levels
• Data acquisition systems with multiple sensor inputs needing RS-232 connectivity

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the supplier provides traceable origin records to guarantee component authenticity and prevent counterfeits.

Selection Notes

Select this model when five driver channels are required alongside three receiver channels. Consider the 250 kb/s speed limit against higher-speed alternatives if system requirements exceed this threshold. Evaluate the SSOP-28 footprint constraints against available PCB space and thermal management needs for the target application environment.

Part Context

This component belongs to the ICL3238 series of RS-232 interface integrated circuits. It shares functional similarities with other devices in the family but is distinguished by its specific configuration of five drivers and three receivers. The part represents a standard solution for legacy serial communication interfacing in modern electronic designs.

Replacement Considerations

ICL3238EIAZ: Identical electrical specifications and pinout; differs only in bulk tube packaging instead of tape-and-reel format.
