ISL3176EIBZ

Overview

The ISL3176EIBZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 3.3V supply and supports data rates up to 20 Mbps. The device features ±15kV IEC61000 ESD protection on RS-485 I/O pins and >7kV HBM protection on other pins. It incorporates full fail-safe receivers, hot-plug circuitry, and true 1/8 unit load capability for up to 256 devices. Operating temperature ranges from -40°C to +85°C with a maximum quiescent current of 800µA.

Procurement Notes

Verify the manufacturer part number ISL3176EIBZ-T against official Renesas documentation to confirm package type and suffix specifications. Ensure compatibility with system voltage requirements and interface standards before procurement.

Selection Notes

Select this component for applications requiring robust ESD protection and high node density on RS-485 buses. Verify that the 3.3V supply voltage aligns with the target system architecture and that the 20 Mbps data rate meets communication speed requirements.

Part Context

This device belongs to the ISL317xE series of low-power, high-speed RS-485/RS-422 transceivers. It shares core architectural features with siblings like the ISL3172E and ISL3175E, differing primarily in pinout configurations and specific driver/receiver characteristics defined by the datasheet.

Replacement Considerations

Cross-reference with ISL3172E or ISL3175E if pinout compatibility allows. Verify functional equivalence regarding ESD ratings and unit load specifications before substitution.
