ICL3245ECBZ-T

Overview

The ICL3245ECBZ-T is an RS-232 transceiver manufactured by Renesas Electronics, belonging to the ICL3245E series. It features a 28-pin SSOP package and supports full-duplex communication with three drivers and five receivers. The device operates on a single power supply ranging from 3 V to 5.5 V, typically utilizing 3.3 V or 5 V rails. It achieves data rates up to 1 Mb/s while maintaining a low operating supply current of 1 mA. Key specifications include enhanced automatic powerdown functionality, 15 kV ESD protection on RS-232 lines, and operation within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Enhanced Automatic Powerdown (E-DWN) circuitry reduces power consumption during idle periods by automatically disabling internal oscillators and charge pumps when no valid signal is present on the receiver inputs.
• Integrated 15 kV electrostatic discharge (ESD) protection on all RS-232 transceiver pins ensures robustness against static discharge events without requiring external protection components.
• Single-supply operation simplifies system design by allowing direct interfacing with standard 3.3 V and 5 V logic families without the need for negative voltage supplies.

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems with RS-232 communication interfaces
• Modems and serial port expansion devices

Procurement Notes

Verify the specific suffix 'CBZ' against official Renesas documentation to confirm exact packaging and moisture sensitivity levels, as distributor listings may vary. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the 0°C to +70°C commercial temperature range aligns with your operational environment constraints before finalizing procurement.

Selection Notes

Select this component when a balance between high-speed 1 Mb/s performance and low power consumption is required in a compact SSOP footprint. It serves as a suitable alternative to legacy Intersil parts for designs needing integrated ESD protection and automatic power management. Consider the 28-pin pinout compatibility if replacing older ICL3245 variants in existing layouts.

Part Context

This part belongs to the ICL3245E family of RS-232 transceivers, originally developed by Intersil and now produced by Renesas Electronics. The family is known for combining high-speed data transmission with ultra-low power features, making it a standard choice for serial communication interfaces in space-constrained electronic applications.

Replacement Considerations
