ICL3217CA-T

Overview

The ICL3217CA-T is an RS-232 transceiver manufactured by Renesas Electronics Corporation, 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 single-ended configuration. Key electrical parameters include a maximum operating temperature of +85 °C and a minimum of -40 °C. It features ESD protection rated at 15 kV for both air gap and human body models. The unit consumes approximately 1 mA during operation and utilizes SOIC-24 surface-mount packaging.

Feature Summary

• Provides integrated charge pumps that eliminate the need for external voltage sources.
• Includes automatic powerdown functionality to minimize standby current consumption.
• Offers robust electrostatic discharge protection on all RS-232 input and output pins.

Applications

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

Procurement Notes

Verify the specific suffix 'CA' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and check for any export restrictions or lifecycle notices such as obsolescence before procurement planning.

Selection Notes

Select this component when designing systems requiring low-power RS-232 communication with single-supply operation between 3 V and 5.5 V. Ensure the design accommodates the required number of drivers and receivers while considering the thermal performance limits defined in the datasheet.

Part Context

This part belongs to the Intersil ICL32X7E family, which was acquired by Renesas Electronics. These devices are designed as low-power replacements for legacy RS-232 transceivers. The ICL3217 variant specifically provides a 1-driver and 3-receiver configuration suitable for complex serial interfaces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with MAX207E or HIN207E only if explicitly stated in the manufacturer's cross-reference documentation.

FAQ

What is the ESD protection rating for the ICL3217CA-T?

The device provides ±15 kV ESD protection on RS-232 I/O pins according to the Human Body Model and ±15 kV Air Gap protection per IEC61000-4-2.

How does the automatic powerdown feature function?

The circuit automatically enters a low-power standby mode when no valid RS-232 signal is detected on the receiver inputs and wakes up immediately upon detection of a valid signal.
