ICL3207IA-T

Overview

The ICL3207IA-T is a low-power RS-232 transceiver manufactured by Intersil, now part of Renesas Electronics. Designed for operation with supply voltages ranging from 3 V to 5.5 V, this device integrates five drivers and three receivers within a single package. It supports data rates up to 500 kb/s while maintaining compatibility with EIA/TIA-232 standards. The component utilizes an SSOP-24 surface-mount package suitable for space-constrained designs. Operating temperatures extend from -40°C to +85°C, ensuring reliability in industrial environments. With a typical operating current of 1 mA, it offers efficient power management for portable applications.

Feature Summary

• Integrates five independent drivers and three receivers for comprehensive serial communication capabilities.
• Operates efficiently on a single 3 V to 5.5 V power supply without requiring external negative voltage generation.
• Features low standby power consumption with automatic powerdown functionality when idle.
• Includes built-in ESD protection on RS-232 I/O pins to enhance signal integrity and device durability.

Applications

• Portable computing devices such as PDAs and palmtops requiring low power interface solutions.
• Industrial equipment utilizing RS-232 communication protocols in harsh environmental conditions.
• Battery-powered peripherals where extended operational life and minimal current draw are critical.

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm temperature range and packaging variations. Confirm RoHS compliance status through current datasheets as manufacturing processes evolve. Check for obsolescence notices or lifecycle changes directly from Renesas Electronics before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring multiple transmit and receive channels within a compact footprint. Ensure the application operates within the specified 3 V to 5.5 V voltage window to maintain signal integrity. Consider the SSOP-24 package dimensions during PCB layout to accommodate thermal requirements and spacing constraints.

Part Context

This device belongs to the ICL32X7E family of low-power RS-232 transceivers designed for 3V systems. It serves as a direct replacement for older 5V-only transceivers like the MAX207E. The ICL3207 variant specifically provides the highest channel count within this series, offering five drivers and three receivers for complex serial interfaces.

Replacement Considerations

The ICL3207CBZ is a pin-compatible alternative available in SOIC-24 packaging. Verify that the substitute maintains the same driver and receiver configuration. Confirm thermal performance matches the original design requirements for the new package type.
