ICL3222EIV-T

Overview

The Intersil ICL3222EIV-T is a dual driver, dual receiver RS-232 transceiver operating from a 3.0V to 5.5V supply. It supports data rates up to 250 kb/s and features full duplex communication in a TSSOP-20 package. The device includes on-chip charge pumps requiring only four 0.1µF capacitors. It provides ±15kV ESD protection on I/O pins per IEC61000 standards. Operating current is 1 mA with automatic power-down reducing standby current to 1 µA. It meets EIA/TIA-232 specifications at 3V.

Feature Summary

Integrated manual and automatic power-down functions for low standby consumption
On-chip voltage converters eliminating external high-voltage supplies
Robust electrostatic discharge protection on all RS-232 pins
Pin-compatible drop-in replacement for legacy 5V devices

Applications

Portable computers and notebook systems
Personal digital assistants (PDAs)
Palmtop devices
Battery-powered instrumentation

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official Renesas documentation. Ensure the specific grade matches industrial temperature requirements if applicable. Cross-reference manufacturer part numbers to avoid obsolete variants.

Selection Notes

Select this component for applications requiring low voltage operation below 5V. It serves as a direct upgrade for MAX242E and SP312E designs. Verify capacitor values match the 0.1µF requirement for internal charge pumps. Check pin compatibility against existing PCB layouts before implementation.

Part Context

This device belongs to the ICL32xxE family of low-power RS-232 transceivers. It is designed for portable electronics where power efficiency is critical. The series offers compatibility with 3.3V and 5.0V logic levels while maintaining standard RS-232 signal integrity.

Replacement Considerations

Officially documented drop-in replacements include MAX3222E, MAX242E, and SP312E. Verify pinout compatibility before substitution. Ensure voltage levels support the target system's logic thresholds.
