ICL3222ECVZ-T

Overview

The ICL3222ECVZ-T is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and two receivers within a 20-pin TSSOP package. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It supports data rates up to 500 kb/s and features 15 kV ESD protection on all pins. The component functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual receivers and a single driver for flexible interface configurations
• Provides robust 15 kV electrostatic discharge protection on all signal lines
• Operates efficiently with low quiescent current consumption

Applications

• Industrial communication systems requiring RS-232 connectivity
• Portable battery-powered equipment utilizing 3V or 5V logic levels
• Embedded control units needing multiple receive channels

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'E' designation aligns with the required extended industrial temperature range specifications. Ensure compatibility with standard 20-pin TSSOP footprints during PCB layout planning. Cross-reference manufacturer documentation for moisture sensitivity level handling requirements.

Selection Notes

Select this component when a design requires two independent receiver inputs alongside a single transmitter output. Compare against the ICL3221 variant if only one receiver channel is necessary. Evaluate the ICL3232 series if symmetric driver and receiver counts are preferred. Verify that the 500 kb/s speed meets the system's baud rate requirements.

Part Context

This part belongs to the ICL32xxE family of RS-232 transceivers designed for low-power applications. It succeeds earlier Intersil designs under the Renesas Electronics portfolio. The device maintains pin compatibility with industry-standard interfaces while offering enhanced ESD resilience suitable for harsh environments.

Replacement Considerations

The ICL3222ECVZ is the tube-packaged equivalent of this reel version. The ICL3221ECVZ-T offers similar functionality but with only one receiver instead of two.
