ISL32175EFVZ-T

Overview

The ISL32175EFVZ-T is a low-power, half-duplex RS-485 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 10 Mbps. The device features ±16 kV IEC 61000-4-2 ESD protection on the bus pins and includes fail-safe circuitry to ensure a high logic state when inputs are open. It is housed in a 16-pin TSSOP package with an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides robust electromagnetic interference immunity through integrated ESD protection rated at ±16 kV on bus I/O pins.
• Incorporates fail-safe receiver design that maintains a high output state during input disconnection or short-circuit conditions.
• Supports hot-plug operations without causing damage to the device or connected systems.
• Features ultra-low shutdown current consumption for efficient power management in battery-operated applications.

Applications

• Industrial automation control networks
• Building automation and security systems
• Metering infrastructure communication

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as per the latest datasheet revision. Ensure the operating environment falls within the specified -40°C to +125°C thermal limits. Check for any recent product change notices affecting pinout or electrical characteristics.

Selection Notes

Select this component for applications requiring reliable half-duplex communication over long distances. It is suitable for environments with high noise levels due to its EFT and ESD immunity. Consider the 1/8 unit load capability if connecting multiple devices to the bus. Verify compatibility with the system's logic voltage levels.
