ICL3232EIBNZ

Overview

The ICL3232EIBNZ is a dual RS-232 transceiver manufactured by Renesas Electronics, housed in a 16-pin SOIC package. It operates on a single power supply ranging from 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features full-duplex communication with two drivers and two receivers. Key electrical specifications include a quiescent current of 1 µA, an output current capability of 35 mA, and a propagation delay of 150 ns. It provides ±15 kV ESD protection and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated high electrostatic discharge (ESD) protection rated at ±15 kV for enhanced signal line robustness.
• Ultra-low standby power consumption achieved through a 1 µA quiescent current design.
• Compliance with EIA/TIA-232 and V.28/V.24 interface standards for reliable serial communication.

Applications

• Industrial control systems requiring robust serial communication interfaces.
• Portable battery-powered equipment utilizing low-power RS-232 connectivity.
• Embedded devices interfacing with modems or other serial peripherals.

Procurement Notes

Verify the specific suffix 'IBNZ' against official Renesas documentation to confirm the SOIC-16 package variant and industrial temperature grade. Ensure compatibility with existing PCB footprints designed for standard SOIC-16 components. Confirm RoHS compliance status via the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require dual-channel RS-232 transmission with minimal power draw. It is suitable for applications needing ±15 kV ESD tolerance without external protection diodes. Compare pinout compatibility with legacy Intersil designs if migrating from older platforms. Validate voltage levels against the target system's logic family requirements.

Part Context

This part belongs to the ICL3232 series of RS-232 transceivers, originally developed by Intersil and now produced by Renesas. The series is known for its compatibility with earlier ICL3232 designs while offering improved ESD performance. The ICL3232EIBNZ specifically denotes the industrial temperature range version in a surface-mount SOIC package.

Replacement Considerations

The ICL3232EIV-16Z serves as a direct functional substitute in the TSSOP-16 package. For SOIC-16 alternatives, verify pin-to-pin compatibility with other dual RS-232 transceivers from the same manufacturer family.
