ICL3245IVZ-T

Overview

The ICL3245IVZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics. It integrates three drivers and five receivers, supporting full-duplex communication at data rates up to 1 Mb/s. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical quiescent current of 1 mA. It features enhanced automatic powerdown functionality that reduces power consumption during idle periods. The component provides 15 kV ESD protection on all pins and is housed in an SSOP-28 package. It is designed for industrial applications with an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates three independent drivers and five independent receivers for complex serial communication topologies.
• Features enhanced automatic powerdown mode to minimize power consumption when the bus is idle.
• Provides robust electrostatic discharge protection rated at 15 kV across all signal pins.

Applications

• Industrial control systems requiring reliable RS-232 connectivity.
• Portable battery-powered equipment utilizing low-voltage operation.
• Communication interfaces in harsh environments needing high ESD immunity.

Procurement Notes

Verify the specific suffix IVZ against official Renesas documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with existing PCB footprints for the SSOP-28 package. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent damage during manufacturing processes.

Selection Notes

Select this component when a design requires multiple receive lines alongside fewer transmit lines within a single IC. Compare against standard CMOS alternatives to evaluate the benefit of integrated ESD protection and lower standby current. Consider the thermal performance of the SSOP-28 package if high ambient temperatures are expected in the final application environment.

Part Context

This part belongs to the ICL3245 family of RS-232 transceivers, which are successors to earlier Intersil designs acquired by Renesas. The family is characterized by its ability to operate directly from single 3-V or 5-V supplies without requiring external charge pumps. The IVZ suffix typically denotes a specific industrial temperature range and tape-and-reel packaging variant within the broader product line.

Replacement Considerations

Direct pin-compatible replacements include the ICL3245EIAZ-T and ICL3245CAZ-T. Verify that alternative versions match the required operating temperature range and driver/receiver count. Check datasheets for any differences in ESD protection ratings or powerdown threshold voltages before substituting.
