ICL3217EIBZ

Overview

The ICL3217EIBZ is a low-power RS-232 transceiver manufactured by Intersil, operating within a supply voltage range of 3.0V to 5.5V. It integrates one driver and three receivers with data rates up to 500 kb/s. The device features automatic powerdown functionality, reducing standby current to 1 µA. It provides ±15kV ESD protection on RS-232 pins per IEC61000-4-2 standards. Packaged in SOIC-24 for surface mount installation, it operates between -40°C and +85°C.

Feature Summary

• Automatic powerdown circuit reduces standby supply current to 1 µA when no valid RS-232 signal is present.
• Integrated charge pumps enable operation from a single 3V to 5.5V supply without external components.
• Provides robust ±15kV ESD protection on all RS-232 input and output pins.

Applications

• ISDN Terminal Adaptors
• Portable Digital Assistants (PDAs) and Palmtops
• Notebook and Laptop Computers

Procurement Notes

Verify the specific suffix 'BZ' against official Renesas/Intersil documentation to confirm lead-free status or packaging variations. Confirm end-of-life status as distribution channels may list discontinued inventory. Ensure compliance with export restrictions if applicable to the region.

Selection Notes

Select this component for battery-powered systems requiring minimal standby current. Verify that the 500 kb/s speed meets system requirements. Ensure the SOIC-24 footprint fits the PCB layout. Compare against MAX207E or HIN207E equivalents if migrating designs.

Part Context

The ICL3217E series belongs to Intersil's 3V RS-232 family, designed to replace older 5V-only transceivers. It targets portable electronics where power efficiency is critical. The 'E' suffix typically denotes extended temperature ranges, while 'IBZ' specifies the package and termination type.

Replacement Considerations

MAX207E, HIN207E, HIN237E are listed as functional replacements in datasheets. Verify pin compatibility and electrical specifications before substitution.
