ICL3243IV

Overview

The ICL3243IV is a single-driver, five-receiver RS-232 transceiver from the Intersil ICL32XX family. It operates on a single power supply ranging from 3.0V to 5.5V and supports data rates up to 250kbps. The device integrates on-chip voltage converters requiring only four external 0.1µF capacitors. It features manual and automatic powerdown modes that reduce standby current to 1µA. The component provides 15kV ESD protection and meets EIA/TIA-232 specifications at 3V operation.

Feature Summary

Integrates charge pumps for RS-232 voltage generation using minimal external components
Supports low-power applications through automatic and manual powerdown functions
Provides robust signal integrity with receiver hysteresis and high ESD protection

Applications

Portable devices such as PDAs and Palmtops
Notebook and laptop computers
Battery-powered systems requiring low standby current

Procurement Notes

Verify the suffix IV indicates the industrial temperature range and SOIC-28 package configuration. Confirm RoHS compliance status and Pb-Free Plus Anneal availability in the specific ordering information. Ensure the source document matches the manufacturer Renesas or Intersil official datasheet for accurate pinout and electrical characteristics.

Selection Notes

Select this component when a single driver and multiple receivers are required for RS-232 communication. It is suitable for mixed 3.3V and 5.0V system environments. Consider the ICL3243IV over standard MAX3243 equivalents if lower power consumption and integrated powerdown features are prioritized for portable designs.

Part Context

The ICL3243IV belongs to the ICL32XX series of low-power RS-232 transceivers. This family is designed as drop-in replacements for legacy parts like the MAX3243. The device targets applications where board space savings and extended battery life are critical constraints.

Replacement Considerations

The datasheet lists the ICL3243 as a drop-in replacement for the MAX3243 and SP3243. Verify pin compatibility and electrical parameter alignment before substitution.
