ICL3207CAZ

Overview

The ICL3207CAZ is a low-power RS-232 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 250 kb/s. 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 utilizes a 24-pin SSOP surface-mount package and is rated for an industrial temperature range of -40°C to +85°C. The component includes 15 kV ESD protection on all pins and complies with RS-232 standards.

Feature Summary

• Integrates five independent drivers and three receivers for complex serial interface requirements.
• Features ultra-low power consumption with a shutdown mode that reduces supply current to less than 1 µA.
• Provides robust electrostatic discharge protection of 15 kV on driver outputs and receiver inputs.
• Operates reliably across the extended industrial temperature range without external components.

Applications

• Industrial control systems requiring multiple serial connections
• Portable battery-powered equipment due to low power profile
• Modems and fax machines utilizing standard RS-232 protocols

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm the exact temperature grade and packaging variant. Confirm end-of-life status and lead times through authorized distributors, as availability may be limited. Ensure compliance with RoHS directives and moisture sensitivity levels before integration into production schedules.

Selection Notes

Select this component when designing systems requiring five transmit and three receive channels within a compact footprint. It is suitable for applications needing high ESD immunity and operation from a single 3 V or 5 V supply. Compare performance against the ICL3207IAZ for industrial temperature ranges or the ICL3207ECAZ for commercial grades and higher speed capabilities.

Part Context

The ICL3207CAZ belongs to the Intersil (now Renesas) ICL3207 family of low-power RS-232 transceivers. This series is designed to replace older discrete solutions by integrating charge pumps and drivers into a single CMOS chip. The CAZ suffix typically denotes the industrial temperature range and SSOP-24 packaging configuration within the broader product line.

Replacement Considerations

Direct pin-compatible alternatives include the ICL3207IAZ for industrial temperature specifications and the ICL3207ECAZ for commercial temperature ranges. Verify electrical parameters such as data rate and ESD protection levels when substituting with other RS-232 transceivers from different manufacturers.
