ICL3222IA

Overview

The ICL3222IA 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 systems. The device integrates two drivers and two receivers with a maximum data rate of 250 kb/s. Key electrical specifications include an operating supply current of 1 mA and ESD protection rated at 15 kV. It functions reliably across an industrial temperature range from -40°C to +85°C and is housed in an SSOP-20 surface-mount package.

Feature Summary

• Integrates dual drivers and receivers for full-duplex RS-232 communication
• Provides 15 kV electrostatic discharge (ESD) protection on all pins
• Operates efficiently with low power consumption suitable for battery-powered applications

Applications

• Industrial control systems requiring robust serial communication
• Portable equipment utilizing 3V or 5V power supplies
• Modem and peripheral interface connections

Procurement Notes

Verify the specific suffix 'IA' against the manufacturer's official documentation to confirm pinout compatibility and RoHS status. Ensure the SSOP-20 package dimensions match the target PCB footprint. Confirm moisture sensitivity level requirements for reflow soldering processes prior to procurement.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with high ESD tolerance. It is appropriate for designs needing operation between 3V and 5.5V without external charge pumps. Compare performance against single-driver alternatives if only one channel is needed to optimize board space.

Part Context

This part belongs to the ICL3222 series of RS-232 transceivers. It shares functional similarities with other devices in the family but differs in package type and specific manufacturing revisions. The 'IA' designation typically indicates a specific tape-and-reel or tube packaging variant and compliance status defined by Renesas.

Replacement Considerations

Direct substitutes may include the MAX3222 or SP3222 series, provided pin compatibility and voltage ranges are verified. Ensure that any replacement maintains the same 250 kb/s data rate and ESD protection levels.
