ICL3221EFVZ-T

Overview

The ICL3221EFVZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver in a 16-pin TSSOP package, supporting full-duplex communication with data rates up to 250 kbps. The device operates on a single power supply ranging from 3 V to 5.5 V and consumes approximately 1 mA of quiescent current. It features an industrial temperature range of -40°C to +85°C and includes 15 kV ESD protection on all pins.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors
• True RS-232 signal levels ensure compatibility with standard protocols
• High electrostatic discharge protection enhances system reliability

Applications

• Industrial control systems requiring robust serial communication
• Portable battery-powered equipment due to low power consumption
• Modems and fax machines utilizing RS-232 interfaces

Procurement Notes

Verify the specific suffix 'EFVZ' against official Renesas documentation to confirm the exact temperature grade and packaging configuration. Ensure that the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single-channel RS-232 interface is required within the industrial temperature range. Compare it against similar models like the ICL3221ECVZ-T if commercial temperature grades are sufficient. Consider the 16-TSSOP footprint constraints during PCB layout design to ensure proper thermal management and signal integrity.

Part Context

This part belongs to the ICL3221 series of low-power RS-232 transceivers. It shares functional similarities with other members of the family but differs in package type and operating temperature specifications. The series is designed for applications needing reliable serial data transmission with minimal external component count.
