ISL32172EIVZ

Overview

The ISL32172EIVZ is a quad RS-422 driver manufactured by Renesas Electronics Corporation, housed in a 16-lead TSSOP surface-mount package. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device delivers a data rate of 32 Mb/s with four independent drivers and zero receivers. It draws a maximum operating supply current of 800 uA and provides 15 kV ESD protection on the bus pins. The component functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides four independent differential drivers for RS-422 communication
• Features high electrostatic discharge (ESD) immunity rated at 15 kV
• Supports low power consumption with an operating current of 800 uA
• Operates over an extended industrial temperature range up to 125°C

Applications

• Industrial control systems requiring robust serial communication
• Data acquisition networks utilizing RS-422 standards
• Point-to-point or multi-drop communication links in harsh environments

Procurement Notes

Verify the specific suffix 'IVZ' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives and moisture sensitivity level requirements for your assembly process. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when a quad driver configuration is required without integrated receivers. Compare performance metrics such as data rate and ESD protection against other RS-422 interface ICs. Consider the TSSOP-16 footprint constraints and thermal dissipation capabilities for your PCB layout design.

Part Context

This part belongs to the ISL32172E series of RS-422 interface integrated circuits. It is designed for high-speed data transmission in noisy industrial environments. The series typically includes variants with different packaging options and termination styles to suit various manufacturing needs.

Replacement Considerations

Check for direct pin-compatible substitutes within the ISL3217xE family. Verify electrical parameters such as supply voltage and data rate match the original design requirements before substitution.
