ICL3225CAZ-T

Overview

The ICL3225CAZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for serial communication applications. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mbps. The device integrates two drivers and two receivers in a single package, providing full-duplex communication capabilities. It features enhanced automatic powerdown functionality to minimize current consumption during idle periods, with an operating supply current of approximately 1 mA. The component includes ±15 kV electrostatic discharge (ESD) protection on all pins, ensuring robust performance in industrial environments. It is housed in a 20-pin SSOP surface-mount package.

Feature Summary

• Integrated dual drivers and dual receivers for full-duplex RS-232 communication
• Enhanced automatic powerdown circuitry reduces standby power consumption
• High ESD protection rating of ±15 kV on all signal pins
• Single-supply operation compatible with 3 V and 5 V logic levels

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered devices utilizing low-power interface standards
• Embedded systems connecting microcontrollers to RS-232 peripherals
• Modem interfaces in telecommunications equipment

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm pinout compatibility and temperature grade. Ensure the ordering code matches the exact package variant required for your PCB layout. Cross-reference the manufacturer's latest datasheet revision to validate RoHS compliance status and any recent packaging changes before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require full-duplex RS-232 connectivity with minimal power draw. It is suitable for applications needing ±15 kV ESD protection without external components. Compare driver/receiver counts against other family members if only single-ended transmission is needed. Verify that the 20-pin SSOP footprint aligns with existing board designs or allows for appropriate routing adjustments.

Part Context

This part belongs to the ICL3225E series of RS-232 transceivers from Renesas, formerly Intersil. The series is known for combining high performance with low power consumption. The 'CAZ' designation typically indicates specific commercial temperature range and packaging variations within the broader ICL3225 product line. It serves as a direct replacement for legacy CMOS RS-232 drivers in modern low-voltage systems.

Replacement Considerations

ICL3225EIAZ-T is a documented alternative offering similar 2/2 driver/receiver configuration in a 20-SSOP package. Verify electrical parameters such as data rate and supply voltage compatibility before substitution. Check for any differences in ESD protection ratings or package dimensions that might impact mechanical fit.
