ICL3225CA

Overview

The ICL3225CA is a dual driver/receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mbps. The device features enhanced automatic powerdown functionality, reducing operating supply current to approximately 1 mA in standby mode. It provides ±15 kV electrostatic discharge (ESD) protection on all RS-232 lines. The component is available in multiple packages including SSOP-20 and PDIP-20, with specific suffixes denoting package type and temperature range.

Feature Summary

• Enhanced automatic powerdown circuitry for low-power operation
• Integrated ±15 kV ESD protection on signal lines
• Single-ended receiver input configuration
• Full-duplex communication capability

Applications

• Industrial control systems requiring serial communication
• Portable battery-powered equipment utilizing RS-232 interfaces
• Modem and peripheral interface circuits

Procurement Notes

Verify the exact suffix against official datasheets to confirm package style and temperature rating. Confirm RoHS compliance status through manufacturer documentation. Check for moisture sensitivity levels if surface-mount variants are selected. Ensure pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select based on required package type such as SSOP or PDIP. Verify that the operating temperature range meets environmental specifications. Consider the 1 mA standby current for battery-sensitive designs. Confirm data rate requirements do not exceed 1 Mbps limits.

Part Context

This component belongs to the ICL3225E series of RS-232 transceivers. It shares functional similarities with other members like the ICL3225ECAZ-T but differs in packaging and specific electrical characteristics defined by the suffix. It serves as a bridge between microprocessors and RS-232 compliant devices.

Replacement Considerations

ICL3225EIAZ-T offers similar functionality in a 20-SSOP package. ICL3225ECPZ provides a through-hole PDIP-20 alternative. Verify pin compatibility and electrical parameters before substitution.
