Introduction

The ISO7041 device is an ultra-low-power multi-channel digital isolator that can be used to isolate CMOS or LVCMOS digital I/Os. The logic input and output buffers of each isolation channel are isolated by a double-capacitor silicon dioxide (SiO₂) insulating gate. The innovative edge-based architecture combined with the on-off keying modulation scheme enables these isolators to have very low power consumption while meeting the 3000Vᵣₘₛ isolation rating specified by UL1577. The dynamic current consumption per channel of this device is less than 120μA/Mbps, and the static current consumption per channel at 3.3V is 3.5μA, allowing the ISO7041 to be used in system designs with limited power consumption and thermal performance. This device can operate with a supply voltage as low as 2.25V and up to 5.5V, and can achieve full functionality with different supply voltages on each side of the isolation barrier. The four-channel isolator is available in a 16-QSOP package with three forward channels and one reverse channel. This device has options for default output high and low levels. If there is a loss of input power or signal, the ISO7041 device without the F suffix defaults to an output high level, and the ISO7041F device with the F suffix defaults to an output low level.
