TIISO7710DWR

Overview

The ISO7710DWR is a high-performance, single-channel digital isolator providing 5000Vrms isolation using Texas Instruments' capacitive silicon dioxide (SiO2) barrier technology. It supports data rates up to 100Mbps with high common-mode transient immunity of 85kV/us, making it suitable for protecting low-voltage circuitry from high-voltage noise and surges in harsh environments. This specific variant features a default-high output state and is housed in a wide-body 16-SOIC package for increased creepage and clearance.

Why Choose This Part

This device offers a very low propagation delay of 11ns (typical at 5V), enabling high-speed timing-critical communications. It operates over a wide supply range of 2.25V to 5.5V, allowing it to function as a level shifter while providing galvanically isolated data transfer. Furthermore, its robust EMC performance and wide temperature rating of -55C to 125C ensure reliability in extreme industrial and automotive settings.

Applications

Getting Started

To evaluate this component, use the ISO7710EVM evaluation module which provides headers for easy signal probing. Ensure that bypass capacitors of 0.1uF are placed as close as possible to the VCC pins on both the primary and secondary sides to maintain signal integrity at 100Mbps. When designing the PCB, maintain the keep-out area under the isolator to preserve the 5000Vrms isolation rating provided by the wide-body SOIC package.
