ICL3207CBZ

Overview

The ICL3207CBZ is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates five drivers and three receivers within a single package, supporting data rates up to 250 kbps. The device operates from a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It is housed in a 24-pin SSOP or SOIC package and functions within an industrial temperature range of -40°C to +85°C. The component includes ESD protection features and complies with RoHS standards.

Feature Summary

• Integrates five drivers and three receivers for comprehensive RS-232 communication capabilities.
• Operates on a single 3 V to 5.5 V power supply with low quiescent current consumption.
• Includes built-in electrostatic discharge (ESD) protection for signal lines.

Applications

• Industrial control systems requiring serial communication interfaces.
• Portable battery-powered equipment due to low power consumption.
• Modems and fax machines utilizing RS-232 protocols.

Procurement Notes

Verify the specific package variant, as the CBZ suffix typically denotes a lead-free plastic SOIC or SSOP configuration. Confirm moisture sensitivity level requirements for surface mount assembly processes. Ensure compatibility with existing RS-232 voltage levels and interface standards before integration into new designs.

Selection Notes

Select this component when a high channel count (five drivers, three receivers) is required in a compact form factor. It is suitable for applications needing operation across a wide temperature range without external charge pumps. Compare against similar Intersil/Renesas models like the ICL3207EIA for pinout and packaging differences.

Part Context

This part belongs to the ICL3207 series of low-power RS-232 transceivers originally developed by Intersil and now produced by Renesas. The series is designed to replace older, higher-power RS-232 solutions. It shares functional similarities with other multi-driver transceivers but is distinct in its specific driver/receiver ratio and low-current specifications.

Replacement Considerations

Direct substitutes include the MAX3207 from Texas Instruments, which offers compatible functionality. Other potential replacements are the ST3207 from STMicroelectronics. Verify pin compatibility and electrical characteristics before swapping components in existing circuits.
