ICL3245CAZ

Overview

The ICL3245CAZ is an RS-232 interface transceiver manufactured by Renesas Electronics. It operates on a single power supply ranging from 3 V to 5.5 V, with typical operation at 3.3 V or 5 V. The device integrates three drivers and five receivers, supporting full-duplex communication at data rates up to 1 Mb/s. It is housed in a 28-pin SSOP package designed for surface mount installation. The component functions within an operating temperature range of 0 °C to +70 °C and draws a maximum operating supply current of 1 mA.

Feature Summary

• Integrates three independent drivers and five independent receivers for multi-channel serial communication
• Supports full-duplex data transmission over standard RS-232 interfaces
• Operates efficiently with low quiescent current consumption under single-supply conditions

Applications

• Industrial control systems requiring reliable serial data exchange
• Embedded devices utilizing RS-232 connectivity for configuration or monitoring
• Communication modules in equipment operating within commercial temperature ranges

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm the industrial/commercial temperature grade and lead-free status. Ensure the SSOP-28 footprint matches the target PCB design. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent package damage during manufacturing processes.

Selection Notes

Select this component when three transmit and five receive channels are required within a compact surface-mount form factor. It is suitable for applications needing 1 Mb/s throughput without the complexity of higher-speed interfaces. Consider the 0 °C to +70 °C operating range; if extended temperature performance is necessary, verify alternative variants such as the E-grade series.

Part Context

This part belongs to the ICL3245 family of RS-232 transceivers produced by Renesas Electronics, formerly Intersil. The family includes variations like the ICL3245EIAZ-T which offers extended temperature ratings and tape-and-reel packaging. The CAZ designation specifically identifies the commercial temperature grade version in the SSOP-28 package.

Replacement Considerations

The ICL3245EIAZ-T serves as a verified substitute offering identical electrical specifications but with an extended operating temperature range of -40 °C to +85 °C. Other family members may differ in packaging or temperature ratings.
