ICL3207CB

Overview

The ICL3207CB is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates five drivers and three receivers within a 24-SOIC package. The device supports data rates up to 250 kbps and operates on a single power supply ranging from 3 V to 5.5 V. It complies with EIA/TIA-232 and V.28/V.24 specifications. The component features an operating temperature range of 0°C to 70°C and includes a receiver hysteresis of 300 mV for noise immunity.

Feature Summary

• Integrates five independent drivers and three independent receivers for comprehensive serial communication
• Supports full-duplex operation compliant with standard RS-232 protocols
• Operates efficiently on a single low-voltage power supply without requiring external negative voltage generation

Applications

• Industrial control systems requiring robust serial interface connectivity
• Embedded devices utilizing microcontrollers for RS-232 communication
• Peripheral equipment interfacing in commercial electronics

Procurement Notes

Verify the current lifecycle status, as this component may be discontinued or subject to last-time buy restrictions. Confirm RoHS compliance requirements against specific project standards, noting that some variants may not meet current environmental directives. Validate the 24-SOIC package dimensions and moisture sensitivity level prior to PCB assembly planning.

Selection Notes

Select this component when a high channel count (5 drivers/3 receivers) is required in a compact surface-mount form factor. Ensure the application environment remains within the 0°C to 70°C industrial temperature range. Verify that the 250 kbps maximum data rate meets system timing requirements and that the 3 V to 5.5 V supply voltage aligns with the target platform's power architecture.

Part Context

The ICL3207CB belongs to the ICL3207 series of RS-232 transceivers produced by Renesas Electronics. This series is designed for applications needing multiple serial channels within limited board space. The CB suffix specifically denotes the SOIC package variant and commercial temperature grade, distinguishing it from other packaging or extended temperature options available in the broader family.

Replacement Considerations

Direct pin-compatible substitutes include the ICL3207EIA and ICL3207IAZ. Note that these alternatives may offer extended temperature ranges (-40°C to 85°C) or different packaging configurations. Verify electrical parameters and package dimensions before substitution.
