ICL3245CB

Overview

The ICL3245CB is a triple line transceiver manufactured by Renesas Electronics Corporation, originally developed under the Harris Corporation brand. It supports RS-232 communication protocols with three drivers and five receivers in a full-duplex configuration. The device operates on a single 3V to 5.5V power supply and features a data rate of up to 1Mbps. It is housed in a 28-pin SOIC package suitable for surface mount installation. The component functions within an operating temperature range of 0°C to 70°C and includes enhanced automatic powerdown capabilities to reduce current consumption.

Feature Summary

• Integrates three independent drivers and five independent receivers for comprehensive RS-232 connectivity.
• Incorporates enhanced automatic powerdown circuitry to minimize power consumption during idle periods.
• Operates reliably from a single positive voltage supply ranging from 3V to 5.5V.

Applications

• Industrial control systems requiring serial communication interfaces.
• Portable battery-powered equipment utilizing low-power RS-232 links.
• Data acquisition modules interfacing with modems or terminals.

Procurement Notes

Verify the manufacturer designation carefully, as the part was originally produced by Harris Corporation before being acquired by Intersil and subsequently Renesas Electronics. Confirm that the specific suffix matches the required package type and temperature grade. Ensure compliance with current RoHS directives if applicable to your assembly process. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a triple driver and five receiver configuration is necessary for RS-232 applications. Consider the 1Mbps data rate limit for high-speed requirements. Evaluate the 28-SOIC package dimensions against available PCB space. Compare power consumption metrics against other transceivers if battery life is a critical design constraint.

Part Context

This component belongs to the ICL324x family of RS-232 transceivers. It shares functional similarities with the ICL3243 but offers a different driver-to-receiver ratio. The product lineage traces back to Harris Semiconductor, now managed by Renesas Electronics. It serves as a standard interface solution for legacy and modern serial communication needs.

Replacement Considerations

The MAX3243EIDW from Texas Instruments is listed as an upgrade substitute. Verify electrical parameter compatibility and pin alignment before replacement. Check for any differences in powerdown behavior or package dimensions.
