ISL3176EIBZ-T

Overview

The ISL3176EIBZ-T is a single RS-485 transceiver manufactured by Renesas Electronics, housed in a 14-lead SOIC package. It operates on a fixed 3.3 V supply voltage and supports data rates up to 20 Mb/s. The device integrates one driver and one receiver with IEC 61000-4-2 ESD protection rated at ±15 kV (air discharge) and ±8 kV (contact discharge). It functions within an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Provides robust IEC 61000-4-2 electrostatic discharge protection for harsh environments
• Supports high-speed differential data transmission up to 20 megabits per second
• Operates reliably across the extended industrial temperature spectrum

Applications

• Industrial automation control networks
• Building management systems
• Factory floor communication buses

Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure component authenticity. Confirm that the delivered units match the exact ISL3176EIBZ-T designation, as suffix variations may indicate different packaging or testing standards. Cross-reference the datasheet revision against the provided documentation to validate parameter consistency before integration into production lines.

Selection Notes

Select this component when a single half-duplex RS-485 interface is required with integrated high-voltage ESD protection. It is suitable for designs constrained to a 3.3 V power rail where moderate data throughput is sufficient. Ensure the application environment remains within the specified -40 °C to +85 °C operational limits for guaranteed performance.

Part Context

This part belongs to the ISL3176E series of RS-485 transceivers from Renesas. It shares functional similarities with other members like the ISL3175E but differs in pin count and package configuration. The series targets reliable serial communication in noisy industrial settings requiring standardized protocol support.

Replacement Considerations

Direct substitutes include the ISL3175EIBZ-T for similar functionality in an 8-pin package. Verify electrical compatibility and pinout alignment before swapping components in existing layouts.
