ISL32174EIVZ

Overview

The ISL32174EIVZ is an RS-422 driver integrated circuit manufactured by Renesas Electronics Corporation. It features four drivers and zero receivers, supporting data rates up to 32 Mb/s. The device operates on a single power supply ranging from 3.0 V to 5.5 V, with a typical operating supply current of 800 uA. It is housed in a 16-lead TSSOP package and supports operation across an extended temperature range from -40°C to +125°C. The component includes robust ESD protection rated at 15 kV.

Feature Summary

• Provides high-speed differential signaling for RS-422 communication standards
• Integrates four independent drivers within a compact surface-mount package
• Features enhanced electrostatic discharge protection for reliable operation in noisy environments

Applications

• Industrial control systems requiring robust serial communication
• Data acquisition networks utilizing RS-422 interfaces
• Multi-drop communication buses in harsh electrical environments

Procurement Notes

Verify the specific suffix IVZ against official Renesas documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the source is an authorized distributor to guarantee authenticity and traceability of the component.

Selection Notes

Select this component when a quad-driver RS-422 interface is required without integrated receivers. Compare against the ISL32172EFBZ for alternative packaging options such as SOIC-Narrow. Verify that the 32 Mb/s data rate meets system requirements and that the 16-lead TSSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to the ISL3217xE series of high-speed RS-422/RS-485 interface devices. It shares functional similarities with other members like the ISL32173EFVZ but differs in protocol support and receiver integration. The series is designed for industrial applications demanding high noise immunity and wide operating temperature ranges.

Replacement Considerations

The ISL32172EFBZ is a documented substitute offering identical electrical performance in a different SOIC-Narrow-16 package. Verify pin compatibility and thermal characteristics before substitution.
