ICL3221ECVZ

Overview

The ICL3221ECVZ is a single driver, single receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features full-duplex communication capability with an operating power current of 1 mA. It provides 15 kV electrostatic discharge (ESD) protection on all pins. The component is housed in a 16-TSSOP surface-mount package and is rated for commercial temperature operation from 0°C to +70°C.

Feature Summary

• Integrated 15 kV ESD protection across all signal pins for enhanced robustness
• Automatic power-down mode reduces quiescent current during idle periods
• Single-ended receiver input configuration compatible with standard RS-232 levels

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered equipment due to low power consumption
• Embedded systems interfacing with RS-232 peripherals

Procurement Notes

Verify the specific suffix 'CVZ' corresponds to the TSSOP-16 commercial grade variant when sourcing. Confirm moisture sensitivity level (MSL 3) requirements for PCB assembly processes. Ensure the supplier provides valid RoHS compliance documentation. Cross-reference the manufacturer part number with official Renesas databases to avoid counterfeit components. Check for any recent product change notices affecting packaging or labeling.

Selection Notes

Select this component for applications requiring a single channel of RS-232 communication with integrated ESD protection. The 250 kb/s data rate suits most standard serial interfaces. Consider the 16-TSSOP package constraints for board layout. Verify that the 0°C to +70°C operating range meets environmental specifications. Compare against higher-speed variants if data throughput requirements exceed 250 kb/s.

Part Context

The ICL3221ECVZ belongs to the ICL3221 series of RS-232 transceivers designed for low-power applications. It shares functional similarities with other members like the ICL3221EIVZ but differs in package type and temperature rating. The series emphasizes compact size and ease of integration into space-constrained designs while maintaining industry-standard RS-232 compatibility.

Replacement Considerations

ICL3221EIVZ offers identical electrical performance in a TSSOP-16 package but supports an extended industrial temperature range (-40°C to +85°C). ICL3221CAZ provides similar functionality in an SSOP-16 package. Verify pinout compatibility and thermal requirements before substituting.
