ICL3241CVZ

Overview

The ICL3241CVZ is a single RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for operation within a 3.0V to 5.5V supply voltage range. It features one driver and one receiver, supporting full-duplex communication with data rates up to 250kbps. The device complies with EIA/TIA-232 and V.28/V.24 standards, ensuring compatibility with standard serial interfaces. It incorporates an on-chip charge pump to generate required voltages from the low supply rail. The component provides ±15kV electrostatic discharge (ESD) protection on both transmitter outputs and receiver inputs, adhering to IEC61000-4-2 air gap and human body model specifications. It operates across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump enables efficient voltage generation from low-voltage supplies
• Robust ±15kV ESD protection ensures reliability in high-interference environments
• Low power consumption with automatic shutdown capabilities for battery-operated systems
• Full compliance with legacy RS-232 interface standards

Applications

• Portable computing devices such as laptops and notebooks
• Personal digital assistants (PDAs) and handheld computers
• Industrial control systems requiring robust serial communication
• Battery-powered equipment needing low standby current

Procurement Notes

Verify the specific suffix 'CVZ' against official Renesas documentation to confirm package type and temperature grade. Ensure the ordering part number matches the exact electrical characteristics required for the target application. Cross-reference with authorized distributors to confirm availability and authenticity. Check for any recent product change notices regarding labeling or manufacturing location updates.

Selection Notes

Select this component when a single channel of RS-232 communication is sufficient for the design. It is suitable for applications requiring low power consumption and high ESD immunity. Compare pinout compatibility with existing designs if replacing older Intersil versions. Ensure the system voltage falls within the 3.0V to 5.5V operating range for optimal performance.

Part Context

This device belongs to the ICL32xxE series of low-power RS-232 transceivers. The series includes variants with multiple drivers and receivers, such as the ICL3241EIVZ which contains three drivers and five receivers. The ICL3241CVZ represents the single-channel configuration within this family, offering similar electrical characteristics and protection features but with reduced pin count and complexity compared to multi-channel counterparts.

Replacement Considerations

MAX3241EIDR from Texas Instruments serves as a functional equivalent. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
