ICL3241ECV

Overview

The ICL3241ECV is a dual RS-232 transceiver manufactured by Renesas Electronics, designed for full-duplex data communication. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device integrates three drivers and five receivers, providing robust signal transmission capabilities. Key electrical specifications include a propagation delay of 0.15 µs and an operating supply current of 1 mA. It features 15 kV electrostatic discharge (ESD) protection on the lines and is housed in an SSOP-28 package suitable for surface mount installation.

Feature Summary

• Integrated shutdown mode for significant power reduction during idle periods
• Built-in charge pump circuitry eliminates the need for external capacitors
• High ESD protection rating ensures reliability in electrically noisy environments

Applications

• Portable equipment requiring low-power serial communication
• Industrial control systems with RS-232 interface requirements
• Modems and fax machines utilizing standard serial protocols

Procurement Notes

Verify the specific suffix 'V' against official Renesas documentation to confirm tape-and-reel packaging or temperature grade variations. Ensure compatibility with existing board layouts regarding the SSOP-28 footprint. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent component damage during manufacturing processes.

Selection Notes

Select this component when a dual-channel RS-232 solution with integrated power management is required. Compare pin counts and driver/receiver configurations against system interface needs. Evaluate the trade-off between the 250 kb/s speed limit and the low power consumption benefits for battery-operated applications.

Part Context

This part belongs to the ICL3241 series of RS-232 transceivers from Renesas. It shares architectural similarities with other members like the ICL3241ECAZ-T but differs in packaging and potential environmental ratings. The series is characterized by its single-supply operation and internal charge pumps, distinguishing it from older dual-supply designs.

Replacement Considerations

Direct substitutes may include the ICL3241ECAZ-T or ICL3241CBZ, provided the package type matches the design constraints. Verify that functional equivalents maintain identical pinouts and electrical characteristics to ensure seamless integration without schematic modifications.
