ICL3245IV-T

Overview

The ICL3245IV-T is a triple RS-232 line transceiver manufactured by Renesas Electronics Corporation. It operates from a single +3V to +5.5V power supply and supports data rates up to 1Mbps. The device features enhanced automatic powerdown functionality, reducing quiescent current to 1 microamp in standby mode. It integrates three drivers and five receivers within a 28-pin SSOP surface-mount package. The component complies with EIA/TIA-232 standards and operates across a commercial temperature range of 0°C to +70°C.

Feature Summary

• Enhanced automatic powerdown circuitry for significant standby current reduction
• Integrated charge pump eliminating the need for external capacitors
• Single-supply operation compatible with standard logic levels

Applications

• Portable battery-powered equipment requiring low power consumption
• Industrial communication systems utilizing RS-232 interfaces
• Modem and fax machine signal processing circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing components. Confirm that the manufacturer designation aligns with Renesas Electronics or authorized Intersil legacy sources. Ensure compliance with RoHS directives if required for the target assembly process. Validate the pinout compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component for applications requiring triple channel RS-232 communication with minimal power draw. The integrated charge pump simplifies board layout by removing external capacitor requirements. Verify that the operating voltage range matches the system's single supply rail. Consider the SSOP package dimensions for space-constrained designs.

Part Context

This part belongs to the ICL3245 family of RS-232 transceivers, originally developed by Intersil and subsequently acquired by Renesas. The series is designed to replace older dual-supply transceivers by enabling operation from a single low-voltage source. The 'IV' designation typically refers to the industrial or commercial grade variant in the SSOP package.

Replacement Considerations

Direct substitutes include the ICL3245EIB and ICL3245CA-T. Verify package equivalence between SSOP and SOIC variants if physical footprint changes are permissible. Check datasheet revisions for any updates to electrical characteristics or pin configurations.
