Introduction

Robust, high-speed, low-power, multi-channel digital isolators are CMOS devices offering substantial data rate, propagation delay, power, size, reliability, and external BOM advantages over legacy isolation technologies. All have CMOS thresholds and Schmitt trigger inputs for high noise immunity and only require VDD bypass capacitors. Data rates up to 150 Mbps are supported, and all devices achieve typical propagation delays of 10 ns. This family includes SPI and QSPI capabilities with direction control pin options. Enable inputs provide a single point control for enabling and disabling outputs. Low power operating modes are provided to optimize power savings. A sleep mode option is included to help conserve power by shutting down active circuits by external pin control. Options include a choice of isolation ratings (3.75 and 6.0 kV_RMS). A fail-safe operating mode controls the default output state during power loss. All products are safety certified by UL, CSA, VDE, and CQC. Products in wide-body packages support voltages of 6.0 kV_RMS with one minute withstand capability per UL 1577. Automotive Grade is available. These products are built using automotive specific flows at all steps in the manufacturing process to ensure the robustness and low defectivity required for automotive applications. Skyworks GreenTM products are compliant with all applicable legislation and are halogen-free.
