Overview
The ISO7841FDWW is a high-performance, quad-channel digital isolator produced by Texas Instruments. This device is designed to provide high isolation ratings, with a 8000VPK isolation voltage, and is certified according to VDE, CSA, CQC, and TUV standards. It features three forward and one reverse-direction channels, making it suitable for a variety of applications requiring robust isolation and low power consumption. The isolator uses a silicon-dioxide (SiO2) insulation barrier to separate the logic input and output buffers, ensuring high electromagnetic immunity and low emissions. The device is available in a 16-pin SOIC wide-body (DWW) package and supports a wide supply range of 2.25 V to 5.5 V, as well as a wide temperature range of –55°C to +125°C.
