ICL3207IAZ-T

Overview

The ICL3207IAZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics, designed for operation with supply voltages ranging from 3 V to 5.5 V. It integrates five drivers and three receivers within a single SSOP-24 package, supporting data rates up to 500 kb/s. The device operates with a typical supply current of 1 mA and functions across an industrial temperature range of -40 °C to +85 °C. It complies with EIA/TIA-232 and V.28/V.24 standards, providing single-ended signal reception and CMOS-compatible inputs.

Feature Summary

• Integrates five independent drivers and three receivers for multi-port serial communication
• Supports dual voltage systems including 3.3 V and 5 V logic levels
• Includes electrostatic discharge protection on RS-232 I/O pins
• Features automatic powerdown functionality to minimize standby current consumption

Applications

• ISDN terminal adaptors requiring low power consumption
• Portable computing devices such as PDAs and palmtops
• Notebook and laptop computer peripheral interfaces

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels due to discontinuation status. Confirm RoHS compliance details and moisture sensitivity level handling requirements before procurement. Ensure the specific suffix matches the required reel or cut tape packaging format for surface mount assembly processes.

Selection Notes

Select this component when designing systems requiring multiple transmit and receive lines in a compact footprint. It serves as a suitable replacement for legacy MAX207E or HIN207E designs where lower voltage operation is necessary. Verify that the 500 kb/s speed meets system timing requirements and that the SSOP-24 package fits the PCB layout constraints.

Part Context

This part belongs to the ICL32X7E family of RS-232 transceivers developed by Intersil, now part of Renesas Electronics. The series targets applications demanding reduced power consumption while maintaining compatibility with standard RS-232 protocols. The IAZ-T suffix indicates a specific tape-and-reel packaging variant intended for automated surface-mount manufacturing.

Replacement Considerations

Publicly confirmed substitutes include the ICL3207CBZ and ICL3207EIA. These alternatives share similar functional specifications but may differ in package type or lead-free status. Verify pinout compatibility and electrical parameters before implementing any cross-reference.
