ICL3207ECAZ-T

Overview

The ICL3207ECAZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics. It integrates five drivers and three receivers within a single package, supporting full-duplex communication compliant with EIA/TIA-232 standards. The device operates on a single power supply ranging from 3 V to 5.5 V. It features an automatic powerdown mode that reduces standby current to approximately 1 µA when no receiver activity is detected. The component utilizes small external capacitors via efficient on-chip charge pumps and provides ±15 kV electrostatic discharge protection on the RS-232 I/O pins.

Feature Summary

• Integrates five independent drivers and three independent receivers for multi-port serial communication
• Features automatic powerdown circuitry that significantly reduces standby current consumption during idle periods
• Provides robust ±15 kV electrostatic discharge protection on all RS-232 input and output pins

Applications

• ISDN Terminal Adaptors requiring multiple serial interfaces
• Portable computing devices such as PDAs and Palmtops where power efficiency is critical
• Peripheral interface circuits in notebook and laptop computers

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.

Selection Notes

Select this component when a design requires five transmit channels and three receive channels within a single IC. It is suitable for applications needing low quiescent current and high ESD immunity. Verify that the system voltage falls within the 3 V to 5.5 V operating range and that the SSOP-24 package fits the board layout constraints.

Part Context

This device belongs to the ICL32X7E family of RS-232 transceivers designed for 3V to 5.5V operation. It serves as a lower power alternative to legacy components like the MAX207E. The family shares common architectural features including automatic powerdown and integrated charge pumps, differing primarily in driver and receiver counts.

Replacement Considerations

Publicly confirmed substitutes include the MAX207E and HIN207E. These components offer similar functionality but may differ in specific electrical parameters or package availability. Verify pin compatibility and performance characteristics before implementation.
