ISL3173EIBZ-T

Overview

The ISL3173EIBZ-T is a low-power RS-485 transceiver manufactured by Renesas Electronics. It operates on a single 3.3 V supply and supports data rates up to 500 kb/s. The device features IEC 61000-4-2 ESD protection rated at ±15 kV (air discharge) and ±8 kV (contact discharge). It is housed in a 14-pin SOIC package with an operating temperature range of -40°C to +85°C. The part includes one driver and one receiver, drawing 800 µA of quiescent current.

Feature Summary

• Integrated high-level ESD protection compliant with IEC 61000-4-2 standards for robust industrial environments.
• Low power consumption design suitable for battery-operated applications with minimal standby current draw.
• Full-duplex operation capability allowing simultaneous transmission and reception on the bus.

Applications

• Industrial automation control systems requiring reliable serial communication.
• Building automation networks utilizing RS-485 protocols.
• Metering equipment such as electricity and gas meters.

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 14-pin SOIC footprint matches the target PCB layout. Ensure the 3.3 V logic level compatibility aligns with the host microcontroller interface requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring moderate data speeds under 500 kb/s with integrated ESD protection. It serves as a direct replacement for older Intersil variants within the same series. Consider thermal dissipation capabilities if multiple units are placed closely together in dense assemblies.

Part Context

This part belongs to the ISL3173E family of RS-485 transceivers from Renesas Electronics. It maintains pinout and functional compatibility with previous generations while offering improved ESD resilience. The product line focuses on providing cost-effective solutions for standard half-duplex serial communication interfaces.

Replacement Considerations

ISL3173EIBZ is the tube-packaged equivalent of the same electrical specification. Other members of the ISL317x series may offer different pin counts or speed ratings but require schematic verification.
