ICL3207ECAZ

Overview

The ICL3207ECAZ is a low-power RS-232 line transceiver manufactured by Renesas Electronics Corporation. It integrates five drivers and three receivers in a single package, supporting full-duplex communication at data rates up to 500 kb/s. The device operates from a single 3 V to 5.5 V power supply with a typical operating current of 1 mA. It features 15 kV electrostatic discharge (ESD) protection on all RS-232 lines and utilizes an automatic power-down mode to minimize energy consumption during idle periods. The component is housed in a 24-pin SSOP package and is rated for operation within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates five independent drivers and three independent receivers for complex serial interface requirements.
• Provides robust 15 kV ESD protection on transmit and receive lines to safeguard connected equipment.
• Incorporates automatic power-down functionality that significantly reduces quiescent current when no signal activity is detected.

Applications

• Industrial control systems requiring multiple serial connections
• Point-of-sale terminals and barcode scanners
• Medical instrumentation with serial communication interfaces

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and tape-and-reel availability. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the ordering code matches the required pin configuration and thermal characteristics for the target PCB layout.

Selection Notes

Select this component when a design requires more than three transmit channels or five receive channels within a single IC. Compare the 500 kb/s speed limit against higher-speed alternatives if system requirements exceed this threshold. Evaluate the 24-pin SSOP footprint constraints against available board space and thermal dissipation capabilities.

Part Context

This part belongs to the ICL3207E series of RS-232 transceivers designed for low-voltage applications. It serves as a bridge between microprocessor logic levels and RS-232 voltage standards. The device is commonly used in embedded systems where space efficiency and power conservation are critical design parameters.

Replacement Considerations

Check for direct pin-compatible upgrades within the Renesas Intersil portfolio. Verify that any substitute maintains the same driver/receiver count and voltage compatibility.
