ICL3217ECV

Overview

The ICL3217ECV is a low-power RS-232 transceiver manufactured by Intersil, now part of Renesas Electronics. 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 one driver and three receivers, featuring an automatic powerdown function that reduces standby current to approximately 1 µA. It provides ±15 kV electrostatic discharge (ESD) protection on RS-232 I/O pins per IEC61000-4-2 standards. Packaged in a 24-pin SOIC format, it meets EIA/TIA-232 and V.28/V.24 specifications.

Feature Summary

• Integrated automatic powerdown circuitry for significant standby power reduction
• Robust ±15 kV ESD protection on RS-232 input and output pins
• Compliance with EIA/TIA-232 and V.28/V.24 interface standards at 3 V operation
• Efficient on-chip charge pump design minimizing external component requirements

Applications

• ISDN Terminal Adaptors
• Portable computing devices such as PDAs and Palmtops
• Notebook and laptop computer serial interfaces
• Peripheral equipment requiring low power consumption

Procurement Notes

Verify the specific suffix 'CV' against official Renesas documentation to confirm package type and temperature grade. Confirm end-of-life status and availability through authorized distributors. Ensure compliance with export restrictions if applicable. Validate RoHS compliance status for the specific manufacturing batch prior to integration into final assemblies.

Selection Notes

Select this component for applications requiring single-supply 3 V to 5.5 V operation with minimal standby current. It serves as a direct replacement for legacy parts like MAX207E or HIN207E in space-constrained designs. Ensure the system architecture utilizes the automatic powerdown feature effectively to maximize battery life in portable implementations.

Part Context

The ICL3217ECV belongs to the ICL32X7E family of RS-232 transceivers designed for low-power mobile applications. This series emphasizes reduced board space through small capacitors and integrated charge pumps. The device is manufactured by Intersil, which was acquired by Renesas Electronics, maintaining continuity in the product line's technical specifications and support.

Replacement Considerations

Publicly confirmed substitutes include MAX207E, HIN207E, and HIN237E. Verify pin compatibility and electrical characteristics before substitution.
