ICL3245CAZ-T

Overview

The ICL3245CAZ-T is a full-duplex RS-232 transceiver manufactured by Renesas Electronics, housed in a 28-pin SSOP package. It operates on a single power supply ranging from 3 V to 5.5 V with a maximum operating current of 1 mA. The device supports data rates up to 1 Mb/s and includes three drivers and five receivers. It features enhanced automatic powerdown functionality to minimize power consumption during idle periods. The component is rated for commercial temperature operation between 0°C and +70°C.

Feature Summary

• Enhanced automatic powerdown circuitry reduces quiescent current significantly when the interface is inactive.
• Integrated charge pump generates required voltage levels for RS-232 signaling without external components.
• Single-supply operation simplifies design integration with standard 3V or 5V logic systems.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Portable battery-powered equipment utilizing low-power RS-232 connectivity.
• Embedded systems needing full-duplex data transmission over short distances.

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with existing PCB footprints for the SSOP-28 package. Cross-reference the manufacturer part number directly with Renesas Electronics to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a full-duplex RS-232 solution with integrated power management is required. It is suitable for designs prioritizing low standby current through automatic powerdown features. Consider the 1 Mbps data rate limit and commercial temperature range constraints. Verify that the 28-pin SSOP form factor fits the mechanical design requirements.

Part Context

This part belongs to the ICL3245 series of RS-232 transceivers, which are designed for high-performance serial communication applications. The series typically offers robust ESD protection and simplified external component requirements. The 'T' suffix indicates tape and reel packaging, facilitating automated assembly processes in manufacturing environments.

Replacement Considerations

Consult official Renesas cross-reference lists for verified substitutes. Generic RS-232 transceivers may lack the specific automatic powerdown characteristics or pinout compatibility. Ensure any replacement maintains the same driver/receiver count and voltage supply range.
