ICL3222IV

Overview

The ICL3222IV is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for full-duplex data communication. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device integrates two drivers and two receivers with a maximum data rate of 250 kb/s. It features low power consumption with an operating current of 1 mA and includes 15 kV ESD protection on all pins. The component is housed in a TSSOP-20 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrated dual driver and receiver configuration for full-duplex RS-232 communication
• Low power operation with 1 mA typical supply current
• Robust electrostatic discharge protection rated at 15 kV
• Single-ended receiver signal processing capability

Applications

• Industrial equipment serial communication interfaces
• Home appliance control panels requiring RS-232 connectivity
• Robotics systems utilizing serial data transmission

Procurement Notes

Verify the specific suffix 'IV' against official Renesas documentation to confirm it denotes the industrial temperature grade (-40°C to +85°C) and TSSOP-20 package variant. Ensure compatibility with system voltage requirements between 3 V and 5.5 V. Confirm moisture sensitivity level handling procedures during assembly, as indicated in manufacturer specifications.

Selection Notes

Select this component when designing systems requiring reliable RS-232 interface functionality with low power constraints. It is suitable for applications needing dual channels without external charge pumps. Verify that the TSSOP-20 footprint matches the PCB layout. Consider the 250 kb/s speed limit for high-speed data transfer requirements.

Part Context

This part belongs to the ICL3222 series of RS-232 transceivers produced by Renesas Electronics, formerly Intersil. The series provides standard RS-232 signal levels using internal charge pump circuitry. The ICL3222IV specifically targets industrial environments due to its extended temperature rating and robust ESD protection characteristics.
