ICL3225EIAZ

Overview

The ICL3225EIAZ is an RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in a 20-SSOP surface-mount package. It operates on a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device integrates one driver and two receivers for full-duplex communication. Key electrical specifications include a maximum operating temperature of +85 °C, a minimum of -40 °C, and an operating supply current of 1 mA. It features 15 kV ESD protection and complies with RoHS standards.

Feature Summary

• Integrated automatic powerdown circuitry that reduces supply current during idle periods
• Enhanced electrostatic discharge (ESD) protection rated at ±15 kV
• Single-ended output drivers compatible with standard RS-232 signaling levels

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered equipment utilizing low-voltage operation
• Data acquisition modules interfacing with PC-based controllers

Procurement Notes

Verify the specific suffix 'EIAZ' corresponds to the SSOP-20 tube packaging configuration. Confirm compliance requirements such as RoHS status and moisture sensitivity level (MSL 2) prior to integration into assembly processes. Ensure the ordering quantity matches the manufacturer's standard tube pack size to avoid handling discrepancies.

Selection Notes

Select this component when a single-driver, dual-receiver RS-232 interface is required in a compact surface-mount form factor. The 250 kb/s data rate suits moderate-speed applications where lower power consumption is prioritized over high-speed throughput. Verify that the 3 V to 5.5 V supply range aligns with the target system's voltage rails.

Part Context

This part belongs to the ICL3225E series of enhanced RS-232 transceivers from Renesas/Intersil. It shares functional similarities with other members like the ICL3222E and ICL3224E but differs in driver/receiver counts and speed ratings. The 'E' designation indicates enhanced features including automatic powerdown and improved ESD protection compared to legacy versions.

Replacement Considerations

The ICL3222EIAZ-T is listed as a parameter-compatible alternative within the same product family. Verify pinout compatibility and ensure the substitute meets the specific 250 kb/s requirement if higher speeds are needed.
