ICL3245EIB-T

Overview

The ICL3245EIB-T is a triple RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in a 28-SOIC package. It supports data rates up to 1Mbps and operates on a single +3V to +5.5V supply. The device features enhanced automatic powerdown functionality, reducing quiescent current to 1 microamp. It complies with EIA/TIA-232 standards and includes Schmitt trigger inputs for noise immunity.

Feature Summary

• Enhanced automatic powerdown mode reduces power consumption significantly during idle periods
• Schmitt trigger receivers provide improved noise immunity on input lines
• Single-supply operation simplifies design integration with standard logic levels

Applications

• Industrial control systems requiring low-power serial communication
• Portable battery-operated equipment utilizing RS-232 interfaces
• Embedded systems needing reliable data transmission in noisy environments

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as historical variants may differ. Check manufacturer documentation for moisture sensitivity level requirements prior to assembly. Ensure the supplier provides valid traceability records for the Renesas brand component.

Selection Notes

Select this component when triple channel RS-232 communication is required with minimal power draw. Compare against standard ICL3245 versions if automatic powerdown is not needed. Verify that the 28-SOIC footprint matches the target PCB layout constraints. Ensure operating temperature range meets the specific environmental conditions of the application.

Part Context

This part belongs to the Intersil/Renesas ICL32xx series of RS-232 transceivers. It shares functional similarities with the ICL3243 but offers three drivers instead of one. The 'EIB' designation typically refers to the industrial temperature grade and SOIC package variant within the broader product family.

Replacement Considerations

The MAX3243EIDW from Texas Instruments is a documented alternative. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement supports the required data rate and voltage range.
