ICL3241EIB-T

Drivers, Receivers, Transceivers Overview

The ICL3241EIB-T is a single RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface-mount package. It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 250Kbps. The device integrates a charge pump for voltage generation and provides ±15kV ESD protection on both driver outputs and receiver inputs. It features low quiescent current of 0.3mA and includes automatic power-down functionality to reduce standby consumption. The component complies with EIA/TIA-232 and V.28/V.24 standards and functions across an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a single driver and single receiver for compact serial communication interfaces
• Includes automatic power-down mode that reduces standby current to microampere levels when the cable is disconnected
• Provides robust ±15kV electrostatic discharge protection on RS-232 pins per IEC61000-4-2 standards

Drivers, Receivers, Transceivers Applications

• Portable computers and laptops requiring low-power serial connectivity
• Personal digital assistants (PDAs) and handheld devices
• Battery-powered systems utilizing 3.3V or 5.0V logic levels

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration compared to tube variants. Confirm RoHS compliance status as manufacturing updates may affect environmental declarations. Ensure the source document explicitly identifies Renesas Electronics Corporation as the manufacturer rather than a distributor listing.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel RS-232 interface is required for space-constrained portable designs. It is suitable for systems needing automatic power management without external hardware changes. Verify compatibility with existing 3.3V and 5.0V mixed-voltage environments before integration into the schematic.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Intersil ICL32xE series of low-power RS-232 transceivers acquired by Renesas. The series is designed for applications where minimizing standby power is critical. The ICL3241 variant specifically offers one driver and one receiver, distinguishing it from multi-driver counterparts like the ICL3241E which contains three drivers.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate generic RS-232 transceivers with similar pinouts and electrical specifications only if official substitution lists are consulted.
