ICL3241ECVZ-T

Overview

The ICL3241ECVZ-T is a single-supply RS-232 transceiver manufactured by Renesas Electronics Corporation, operating within a voltage range of 3.0V to 5.5V. It integrates three drivers and five receivers, ensuring compliance with EIA/TIA-232 and V.28/V.24 standards even at the minimum supply voltage. The device supports data rates exceeding 250kbps under worst-case load conditions and features ±15kV electrostatic discharge protection on both transmitter outputs and receiver inputs. It utilizes an efficient on-chip charge pump to generate required voltages from a single supply. The component is housed in a TSSOP-28 surface-mount package and operates across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates three independent drivers and five independent receivers for complete serial port functionality
• Includes noninverting always-active receivers designed specifically for system wake-up capability
• Provides robust ±15kV electrostatic discharge protection on all RS-232 pins
• Operates efficiently on a single power supply using internal charge pump circuitry

Applications

• Personal Digital Assistants (PDAs)
• Notebook and laptop computers
• Portable computing devices requiring low standby power

Procurement Notes

Verify that the suffix 'T' indicates tape-and-reel packaging when sourcing this specific variant. Confirm the manufacturer designation as Renesas Electronics Corporation or its predecessor IDT/Intersil to ensure authenticity. Check for RoHS compliance markings consistent with the 'E' suffix. Ensure the TSSOP-28 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select the ICL3241ECVZ-T when a design requires multiple transmit and receive lines within a compact form factor. This model is appropriate for systems needing wake-up functionality via noninverting receivers. Consider this part for applications where board space is limited due to its small footprint and requirement for low-value external capacitors. Ensure the system operates within the specified 3.0V to 5.5V range for optimal performance.

Part Context

This component belongs to the ICL32xxE family of low-power RS-232 transceivers. The family includes variants like the ICL3243E which feature automatic power-down modes, whereas the ICL3241E focuses on manual control and wake-up capabilities. The 'ICL' prefix historically denotes Intersil CMOS line products, now managed by Renesas. The 'E' suffix typically signifies extended temperature ranges and enhanced ESD protection compared to older commercial grades.

Replacement Considerations

The ICL3241CBZ is a pin-compatible alternative in SSOP-28 packaging. The MAX3241 from Maxim Integrated offers similar functionality but may require different external capacitor values. Verify electrical compatibility and package dimensions before substituting.
