ICL3245ECB

Overview

The ICL3245ECB is a low-power RS-232 transceiver manufactured by Intersil, designed for operation with supply voltages ranging from 3.0 V to 5.5 V. It integrates three drivers and five receivers within a single package, supporting full-duplex communication at data rates up to 1 Mb/s. The device features enhanced automatic powerdown circuitry that reduces operating supply current to approximately 1 µA when no valid signal is present on the receiver inputs. It provides ±15 kV electrostatic discharge (ESD) protection on all RS-232 lines, ensuring robust performance in harsh environments. The component operates reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Integrated three drivers and five receivers for versatile RS-232 connectivity
• Enhanced automatic powerdown mechanism significantly reduces quiescent current
• High ESD protection rating of ±15 kV on all signal lines
• Single-supply operation compatible with 3 V and 5 V logic levels

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems with high ESD exposure risks
• Communication interfaces in mobile computing devices
• Embedded systems utilizing RS-232 protocols for data transmission

Procurement Notes

Verify the specific suffix 'CB' against official Renesas or Intersil documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the identified package style. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before procurement.

Selection Notes

Select this component when designing circuits that require multiple transmit and receive channels in a compact form factor. The low power consumption makes it suitable for applications where battery life is critical. Ensure the system voltage falls within the 3.0 V to 5.5 V range for optimal performance and adherence to electrical specifications.

Part Context

This part belongs to the ICL32XXE family of RS-232 transceivers known for their low power consumption and high reliability. The ICL3245 variant specifically offers a 3-transmitter and 5-receiver configuration, distinguishing it from other members of the series with different driver/receiver counts. It represents a standard solution for serial communication interfaces in modern electronic designs.

Replacement Considerations

Check for direct replacements such as ICL3245EIB or ICL3245EIAZ if pinout and package dimensions match. Verify functional equivalence regarding data rate and powerdown behavior. Consult the manufacturer's cross-reference guide for any updated versions or alternative packages within the same product line.
