ICL3232CVZ-T

Overview

The ICL3232CVZ-T is a dual RS-232 transceiver manufactured by Renesas Electronics, operating within a supply voltage range of 3.0 V to 5.5 V. It supports data rates up to 250 kbps and features full-duplex communication with two drivers and two receivers. The device operates from a single power source and includes integrated charge pumps for RS-232 voltage generation. It offers ±15 kV ESD protection on all pins and draws only 1 mA of supply current during active operation. The component is housed in a TSSOP-16 surface-mount package and functions reliably across an industrial temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external capacitors
• Robust electrostatic discharge protection rated at ±15 kV on all signal lines
• Low power consumption with 1 mA active supply current draw
• Compliance with EIA/TIA-232 and V.28/V.24 interface specifications

Applications

• Portable equipment requiring RS-232 connectivity
• Modems and fax machines
• Industrial control systems
• Point-of-sale terminals

Procurement Notes

Verify the specific suffix 'CVZ' against the manufacturer's official documentation to confirm the exact temperature grade and packaging configuration. Ensure that the ordering information matches the required RoHS compliance status and moisture sensitivity level as defined in the latest datasheet revision. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a dual-channel RS-232 solution is required for space-constrained designs utilizing a single 3V or 5V power rail. The internal charge pump simplifies board layout by reducing external component count. Consider the 250 kbps speed limit and 0°C to +70°C operating range to ensure compatibility with the target application's performance and environmental requirements.

Part Context

This part belongs to the ICL3232E family of RS-232 transceivers designed for low-power applications. The series provides reliable serial communication interfaces for devices needing to connect to standard RS-232 ports. The CVZ designation indicates a specific commercial temperature grade and tape-and-reel packaging format suitable for automated assembly processes.

Replacement Considerations

Compatible substitutes include the ICL3232EIV-16Z-T and other variants within the ICL3232 series. Verify pinout compatibility and electrical specifications before substitution. Ensure that any replacement part meets the same voltage, current, and ESD protection requirements.
