ICL3241CB-T

Overview

The ICL3241CB-T is a triple line transceiver manufactured by Harris Corporation, operating within the PDSO-28 package. It supports three drivers and five receivers, complying with EIA/TIA-232, V.24, and V.28 standards. The device functions on a single +3V to +5.5V supply voltage. Input characteristics utilize Schmitt triggers for noise immunity. The operational temperature range spans from 0°C to 70°C. The component is RoHS compliant and utilizes plastic epoxy packaging.

Feature Summary

• Integrates three independent drivers and five receivers for serial communication
• Includes noninverting always-active receivers for system wake-up capability
• Features automatic power-down functionality to minimize standby current consumption

Applications

• Portable digital assistants (PDAs)
• Notebook computers
• Laptop computers

Procurement Notes

Verify the manufacturer designation carefully, as Intersil and Renesas are the primary entities associated with this part number lineage. Confirm that the suffix 'T' corresponds to the specific tape-and-reel packaging variant required for automated assembly processes. Ensure the component meets the necessary environmental compliance standards for the target deployment region.

Selection Notes

Select this component when designing systems requiring low-power RS-232 connectivity in space-constrained portable devices. It is suitable for mixed 3.3V and 5.0V system environments. Consider the automatic power-down feature if battery life optimization is critical. Verify that the PDSO-28 footprint aligns with the printed circuit board layout constraints.

Part Context

This device belongs to the ISL32xx family of one-microamp supply-current RS-232 transmitters and receivers. The family includes variants such as the ICL3221, ICL3222, ICL3223, ICL3232, and ICL3243. These components share common design goals of low power consumption and compatibility with modern low-voltage logic systems while maintaining standard RS-232 signal levels.
