ICL3217ECBZ

Overview

The ICL3217ECBZ is an RS-232 transceiver manufactured by Renesas Electronics, belonging to the ICL3217E series. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kb/s. The device integrates one driver and three receivers in a CBZ package. It features low power consumption with a typical operating current of 1 mA and standby current reduced to 1 µA via automatic powerdown. The component provides ±15 kV ESD protection on RS-232 pins and meets EIA/TIA-232 specifications at 3 V operation.

Feature Summary

• Integrated automatic powerdown circuit reduces standby supply current to 1 µA when no valid RS-232 voltage is detected on receiver inputs.
• Provides robust electrostatic discharge protection rated at ±15 kV for both air gap and human body models on RS-232 I/O pins.
• Utilizes efficient on-chip charge pumps requiring only small external capacitors, minimizing board space requirements.

Applications

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

Procurement Notes

Verify the specific suffix 'CBZ' against official Renesas documentation to confirm exact packaging type and lead-free status. Confirm availability as this product line may be subject to discontinuation notices. Ensure compliance with export restrictions if applicable to the destination region. Cross-reference the manufacturer number with current distributor listings to validate authenticity.

Selection Notes

Select this component for designs requiring low-power RS-232 communication in battery-operated portable devices. It serves as a direct replacement for legacy parts like MAX207E or HIN207E where 3 V operation is required. Ensure the application environment stays within the -40°C to +85°C temperature range. Verify that the single driver and three receiver configuration matches the system interface needs.

Part Context

The ICL3217ECBZ belongs to the Intersil/Renesas ICL32X7E family of low-power RS-232 transceivers. This series is designed to replace older 5 V-only devices while maintaining compatibility with EIA/TIA-232 standards. The ICL3217 variant specifically offers one transmitter and three receivers, distinguishing it from other members of the family with different driver/receiver counts.

Replacement Considerations

Officially documented equivalents include MAX207E, HIN207E, and HIN237E. These parts serve as 5 V lower power replacements but require verification of pinout and electrical parameter compatibility before substitution.
