ICL3241CAZ-TS2705

Overview

The ICL3241CAZ-TS2705 is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates three drivers and five receivers within a single package, supporting data rates up to 250 kb/s with a propagation delay of 0.15 us. The device operates on a supply voltage range of 3 V to 5.5 V, including standard 3.3 V and 5 V levels, while consuming only 1 mA of operating current. It features 15 kV ESD protection and includes a shutdown mode for power reduction. The component is housed in a 28-SSOP package with a width of 5.30 mm and is designed for surface mount installation.

Feature Summary

• Integrates three independent drivers and five independent receivers for full-duplex communication
• Provides robust electrostatic discharge protection rated at 15 kV
• Includes an active low shutdown control pin to minimize power consumption during idle periods
• Supports operation across standard 3.3 V and 5 V power supply rails

Applications

• RS-232 serial communication interfaces
• Modem connections
• Portable battery-powered instruments
• Industrial control systems requiring low power consumption

Procurement Notes

Verify the specific suffix TS2705 against official Renesas documentation to confirm packaging configuration and reel specifications. Ensure compatibility with RoHS requirements if mandated by project standards. Confirm that the 28-SSOP footprint matches the target PCB design constraints. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability of the batch.

Selection Notes

Select this component when a high driver-to-receiver ratio is required for complex RS-232 routing. The low quiescent current makes it suitable for battery-operated devices where power efficiency is critical. Consider the 28-SSOP package size relative to available board space. Verify that the 250 kb/s speed meets the application's timing requirements and that the 15 kV ESD rating satisfies environmental safety standards.

Part Context

This part belongs to the ICL3241 series of RS-232 interface integrated circuits from Renesas Electronics. The series is characterized by its ability to operate with a single external charge pump capacitor, simplifying circuit design. These transceivers are widely used in legacy serial communication applications where reliability and moderate data speeds are prioritized over high-speed performance.
