ICL3232CV-T

Overview

The ICL3232CV-T is a dual-driver, dual-receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates from a single +3.0V to +5.5V power supply and meets EIA/TIA-232 and V.28/V.24 specifications at the minimum voltage. The device features on-chip voltage converters requiring only four external 0.1µF capacitors. It supports data rates up to 250kbps and includes ±15kV ESD protection per the human body model. The component is housed in a TSSOP-16 package.

Feature Summary

• Dual drivers and dual receivers for bidirectional serial communication
• On-chip charge pumps eliminate need for external inductors or multiple supplies
• Integrated electrostatic discharge protection for robust signal integrity
• Low standby current capability through automatic powerdown mechanisms

Applications

• Portable battery-powered equipment such as PDAs and palmtop computers
• Notebook and laptop computer serial port interfaces
• Handheld peripherals and printers requiring RS-232 connectivity

Procurement Notes

Verify the specific suffix 'CV-T' against official Renesas documentation to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with target PCB footprint dimensions for the TSSOP-16 package. Cross-reference RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when designing systems requiring low-power RS-232 communication from a single 3V or 5V rail. It serves as a drop-in replacement for legacy MAX3232 devices. Consider the 250kbps speed limit and ±15kV ESD rating against interface requirements. Verify that the TSSOP-16 package fits within the available board space constraints.

Part Context

This part belongs to the ICL32XX family of RS-232 transceivers designed for low-voltage operation. The family includes variants like ICL3221E and ICL3243E with different driver/receiver counts. The ICL3232 specifically provides two drivers and two receivers, balancing complexity and pin count for standard serial applications.

Replacement Considerations

Publicly documented drop-in replacements include the MAX3232 and HIN232. Verify pinout compatibility and electrical parameters before substitution. Alternative packages such as SOIC-16 may require adapter considerations.
