ICL3222ECVZ

Overview

The ICL3222ECVZ is an RS-232 transceiver manufactured by Renesas Electronics, housed in a TSSOP-20 surface-mount package. It operates on a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device features one driver and two receivers with a data rate capability of 500 kb/s. It draws a typical operating supply current of 1 mA and includes 15 kV ESD protection. The component functions within a temperature range of 0°C to +70°C.

Feature Summary

• Integrated 15 kV electrostatic discharge (ESD) protection for enhanced signal line robustness
• Low power consumption architecture with 1 mA typical operating supply current
• Single-ended output configuration compatible with standard RS-232 signaling

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered equipment utilizing low-voltage operation
• Data acquisition modules interfacing with RS-232 peripherals

Procurement Notes

Verify the specific suffix 'CVZ' against the manufacturer's official documentation to confirm pinout compatibility and RoHS status. Ensure that the TSSOP-20 package dimensions align with the target PCB footprint design. Confirm moisture sensitivity level requirements prior to assembly processing.

Selection Notes

Select this component when a single driver and dual receiver configuration is required for half-duplex or full-duplex RS-232 links. It is suitable for designs prioritizing low quiescent current and high ESD immunity over higher data rates exceeding 500 kb/s. Verify that the 0°C to +70°C industrial temperature range meets the environmental constraints of the final application.

Part Context

This part belongs to the ICL3222 series of RS-232 interface integrated circuits from Renesas Electronics. The series provides solutions for converting TTL/CMOS logic levels to RS-232 voltages. The ICL3222 variant specifically offers a simplified channel count compared to multi-driver counterparts in the same family.

Replacement Considerations

Check for direct cross-reference part numbers such as the MAX3222EIA or SP3222EE from other manufacturers. Ensure that any substitute maintains the same TSSOP-20 package, 3V-5.5V supply range, and 500 kb/s data rate specifications.
