ISL32175EIBZ-T

Overview

The ISL32175EIBZ-T is a low-power RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 20 Mb/s. The device features ±15 kV ESD protection on the bus pins, compliant with IEC 61000-4-2 standards. It is housed in an 8-pin SOIC package and functions as a half-duplex transceiver with one driver and one receiver. The operational temperature range spans from -40°C to +85°C.

Feature Summary

• Provides robust electrostatic discharge (ESD) protection rated at ±15 kV on the differential bus lines.
• Supports high-speed data transmission with a maximum rate of 20 megabits per second.
• Operates reliably across a wide industrial temperature range from -40°C to +85°C.

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation matches Renesas or Intersil legacy branding. Ensure the component meets RoHS compliance requirements for your region. Check current availability status as lead times may vary based on production cycles.

Selection Notes

Select this component for applications requiring high-speed RS-485 communication with strong ESD immunity. It is suitable for environments with significant electrical noise or static discharge risks. Verify that the 3.0 V to 5.5 V supply range aligns with the system power architecture. Consider the 8-pin SOIC package constraints for PCB layout space.

Part Context

This part belongs to the ISL32175E series of RS-422/RS-485 interface ICs. It serves as a successor to earlier Intersil designs now managed by Renesas Electronics. The series focuses on providing reliable connectivity for industrial protocols while maintaining low power consumption and high noise immunity.

Replacement Considerations

Direct substitutes include other 20 Mb/s RS-485 transceivers with ±15 kV ESD protection in SOIC-8 packages. Verify pin compatibility and electrical specifications before swapping. Common alternatives may include parts from Texas Instruments or Maxim Integrated families with similar speed and protection ratings.

FAQ
