ICL3241CV

Overview

The Intersil ICL3241CV is a low-power RS-232 transceiver designed for operation with supply voltages ranging from 3.0V to 5.5V. It integrates three drivers and five receivers, providing full serial port functionality suitable for portable systems. The device complies with EIA/TIA-232 and V.28/V.24 standards even at the minimum 3.0V supply voltage. It features ±15kV electrostatic discharge (ESD) protection on both transmitter outputs and receiver inputs. The component operates within a temperature range of -40°C to +85°C and supports data rates up to 250kbps under worst-case loading conditions.

Feature Summary

• Integrated charge pump enables single-supply operation without external inductors
• Automatic power-down mode reduces standby current to microampere levels when cable is disconnected
• Enhanced ESD protection ensures reliability against air gap and human model discharges
• Compatible with 3.3V, 5.0V, and mixed-voltage system architectures

Applications

• Personal Digital Assistants (PDAs)
• Laptop computers
• Portable computing devices
• Handheld terminals

Procurement Notes

Verify the specific suffix 'CV' against official Renesas/Intersil documentation to confirm package type and temperature grade. Ensure the ordering part number matches the required RoHS compliance status and moisture sensitivity level. Cross-reference the manufacturer's latest datasheet to validate pinout compatibility and electrical specifications before procurement.

Selection Notes

Select this component for applications requiring a complete RS-232 interface with minimal external capacitance. The ICL3241CV is appropriate where low standby power is critical due to its automatic shutdown feature. Verify that the system voltage falls within the 3.0V to 5.5V range. Consider the TSSOP or SSOP package availability if board space is constrained.

Part Context

The ICL3241CV belongs to the Intersil ICL32xxE series of RS-232 transceivers. This family is characterized by low power consumption and high ESD tolerance. The device serves as a bridge between TTL/CMOS logic levels and RS-232 signal levels, facilitating communication in battery-powered portable electronics.

Replacement Considerations

The ICL3241EIVZ is a verified equivalent offering identical electrical characteristics and functionality. Check for package differences between CV and IVZ suffixes to ensure mechanical compatibility during replacement.
