ICL3241EIB

Overview

The ICL3241EIB is a triple line transceiver manufactured by Harris Corporation, operating within a supply voltage range of 3.0 V to 5.5 V. It integrates three drivers and five receivers compliant with EIA/TIA-232 and V.28/V.24 standards. The device supports data rates up to 250 kbps and includes an internal charge pump circuit. It features ±15 kV electrostatic discharge protection on RS-232 pins and operates across a temperature range of -40°C to +85°C. The component is housed in a 28-pin SOIC package.

Feature Summary

• Integrates three drivers and five receivers for complete serial port functionality
• Includes internal charge pump circuitry for efficient voltage generation
• Provides enhanced electrostatic discharge protection on all RS-232 I/O pins

Applications

• Notebook computers
• Sub-notebook computers
• Battery-powered equipment

Procurement Notes

Verify the manufacturer designation as Harris Corporation or Intersil/Renesas depending on the production era. Confirm the suffix 'IB' corresponds to the specific SOIC-28 package variant. Ensure compliance with RoHS directives if required for the target assembly process. Cross-reference the datasheet revision date to confirm parameter stability.

Selection Notes

Select this component when a single-chip solution for RS-232 communication is required in portable devices. It is suitable for systems needing three transmit and five receive lines. Verify that the 3.0 V to 5.5 V supply range matches the system power architecture. Consider the 250 kbps data rate limit for high-speed interface requirements.

Part Context

This device belongs to the ICL32xxE series of low-power RS-232 transceivers designed for battery-operated applications. The series emphasizes reduced standby current through auto power-down features. The ICL3241EIB specifically provides the pinout and functionality necessary for standard PC serial ports in compact form factors.

Replacement Considerations

ST3241EB is a verified functional substitute offering identical driver/receiver counts and similar electrical characteristics.
