ICL3221CVZ

Overview

The ICL3221CVZ is a single-driver, single-receiver RS-232 transceiver manufactured by Intersil. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kb/s. The device features an automatic power-down mode that reduces operating supply current to 10 uA. It includes ESD protection rated at 15 kV and offers a propagation delay of 0.3 us. Designed for surface-mount installation, it is housed in a TSSOP-16 package and functions as a full-duplex transceiver compliant with RS-232 standards.

Feature Summary

• Integrates automatic power-down functionality to minimize active power consumption during idle periods.
• Provides robust electrostatic discharge protection on all RS-232 lines to enhance signal integrity.
• Supports standard RS-232 signaling protocols with single-ended receiver inputs.

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems utilizing serial communication interfaces
• Embedded devices needing compact single-channel RS-232 connectivity

Procurement Notes

Verify the specific suffix designation when sourcing this component, as variations such as CVZ-T or CVZ-T7 indicate different packaging formats like cut tape or reel quantities. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity level requirements are met during storage and handling procedures to maintain device reliability.

Selection Notes

Select this component for designs requiring a single driver and receiver pair with minimal quiescent current draw. Compare against higher-channel variants if additional transmit or receive paths are needed. Verify that the TSSOP-16 footprint aligns with the printed circuit board layout constraints and thermal management requirements of the target application environment.

Part Context

This part belongs to the ICL3221 series of RS-232 interface integrated circuits produced by Intersil, now part of Renesas Electronics. The series focuses on providing efficient serial communication solutions for space-constrained applications. Related components in this family may offer increased channel counts or alternative packaging options while maintaining similar electrical characteristics and protocol support.

Replacement Considerations

Direct substitutes include other single-channel RS-232 transceivers from the same manufacturer family. Cross-reference pinouts and electrical specifications carefully when considering alternatives from different vendors to ensure compatibility with existing system architectures and voltage levels.
