ISO7041 Overview
The ISO7041 device is an ultra-low power, multichannel digital isolator that can be used to isolate CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. Innovative edge based architecture bined with an ON-OFF keying modulation scheme allows these isolators to consume very-low power while meeting 3000-VRMS...
