ICL3207ECBZ

Overview

The ICL3207ECBZ 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 with data rates up to 500 kb/s. The device operates from a single power supply ranging from 3 V to 5.5 V, including standard 3.3 V and 5 V rails. It features 1 mA typical operating supply current and includes 15 kV ESD protection on all RS-232 lines. The component is housed in a 24-pin SOIC package and is rated for commercial temperature operation between 0°C and +70°C.

Feature Summary

• Integrates five independent drivers and three independent receivers for comprehensive serial interface connectivity.
• Provides robust electrostatic discharge protection of 15 kV on all signal lines to enhance system reliability.
• Operates efficiently with ultra-low supply current consumption suitable for battery-powered applications.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Portable instrumentation and handheld devices utilizing low-voltage power supplies.
• Data acquisition modules needing multiple RS-232 connections within compact form factors.

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature range. Confirm end-of-life status and lead times through authorized distributors. Ensure compatibility with existing PCB footprints for the 24-SOIC variant. Check for moisture sensitivity levels if storage conditions exceed manufacturer recommendations.

Selection Notes

Select this component when five drivers and three receivers are required in a single IC. Compare performance against the ICL3207IAZ for industrial temperature ranges or the ICL3207ECAZ for SSOP packaging options. Verify that the 500 kb/s speed meets system requirements. Ensure the 3 V to 5.5 V supply range aligns with the target board voltage.

Part Context

This part belongs to the ICL3207 family of low-power RS-232 transceivers. It shares core functionality with variants like the ICL3207CBZ and ICL3207IAZ but differs in package style and specified operating temperature. The EC suffix typically denotes commercial temperature range and SOIC packaging within the Renesas portfolio.

Replacement Considerations

Direct substitutes include the ICL3207CBZ for identical electrical specifications in a SOIC package. The ICL3207ECAZ offers similar features in an SSOP package. Verify pinout compatibility before replacing legacy components from Intersil or other manufacturers.
