ISL32174EIBZ

Overview

The ISL32174EIBZ is a quad RS-422 transmitter manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 32 Mbps. The device features ±16.5kV ESD protection on the differential bus pins, ensuring robust performance in electrically noisy environments. Packaged in a 16-lead SOIC, it is designed for low power consumption applications requiring reliable serial communication.

Feature Summary

• Provides four independent RS-422 drivers for full-duplex communication
• Offers high electrostatic discharge protection on the bus lines
• Supports operation across standard industrial temperature ranges
• Compatible with 3.3V and 5V logic systems

Applications

• Industrial automation control systems
• Building automation networks
• Data acquisition equipment
• Test and measurement instruments

Procurement Notes

Verify the package type matches the required PCB footprint, specifically the 16-lead SOIC configuration. Confirm that the operating temperature range aligns with the specific environmental conditions of the target application. Ensure that the ESD protection levels meet the safety requirements for the intended deployment environment.

Selection Notes

Select this component when multiple isolated RS-422 channels are required within a single integrated circuit. It is suitable for designs prioritizing board space efficiency alongside noise immunity. Consider the low power characteristics for battery-operated or thermally constrained systems where heat dissipation is limited.

Part Context

This part belongs to the ISL3217x series of interface transceivers from Renesas. It complements other variants in the family that may offer different pin configurations or additional receiver capabilities. The series is designed to provide flexible solutions for various serial communication standards in industrial and commercial settings.

Replacement Considerations

Direct substitutes include the ISL32174EIVZ, which shares identical electrical specifications but utilizes a TSSOP-16 package instead of SOIC-16. Verify mechanical compatibility before substitution. Other members of the ISL3217x family may serve as alternatives if pinout differences are acceptable.
