ISL32172EIVZ-T

Overview

The ISL32172EIVZ-T is a quad RS-422 driver manufactured by Renesas Electronics, housed in a 16-lead TSSOP package. It supports data rates up to 32 Mb/s and operates on a single power supply ranging from 3.0 V to 5.5 V. The device features low quiescent current of 800 uA and includes robust ESD protection rated at +/- 15 kV. Designed for industrial environments, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides four differential drivers compliant with RS-422 standards for reliable serial communication.
• Integrates high-level electrostatic discharge protection to safeguard against transient voltage events.
• Operates efficiently with low power consumption suitable for battery-powered or energy-constrained systems.

Applications

• Industrial automation control networks
• Building management and security systems
• Point-to-point multipoint communication links

Procurement Notes

Verify the specific suffix IVZ-T confirms the TSSOP-16 package and reel packaging format. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the supplier provides valid traceability documentation for the Renesas manufacturing origin.

Selection Notes

Select this component when a quad transmitter is required without integrated receivers. Compare against the ISL32172EFBZ-T if an SOIC-16 package or extended temperature range up to 125°C is necessary instead of the standard 85°C limit.

Part Context

This part belongs to the ISL32172E series of interface ICs. It serves as the transmit-only counterpart to receiver variants like the ISL32173EIBZ-T. The series is designed for high-speed serial data transmission in noisy industrial environments requiring standardized differential signaling.

Replacement Considerations

The ISL32172EFBZ-T is a pin-compatible alternative offering the same electrical specifications but utilizes an SOIC-Narrow-16 package and supports an extended operating temperature range up to +125°C.
