Introduction

The SiLM574x devices are high performance, quad channel digital isolator with 5.0 kVRMS (SOP16W) isolation rating per UL1577. The SiLM574x devices provide high electromagnetic immunity and low emissions at low power consumption. The SiLM5740 device has all channels in the same direction, the SiLM5741 device has three channels in forward direction and one channel in reverse direction, and the SiLM5742 device has two channels in forward direction and two channels in reverse direction. In the event of input power or signal loss, the default output is high for devices without suffix F and low for devices with suffix F.
