ADuM120N/ADuM121N Dual-Channel Digital Isolators Analog Devices ADuM120N/ADuM121N Dual-Channel Digital Isolators with iCoupler® technology offer outstanding performance characteristics. The isolators have a low 13ns propagation delay with a pulse width distortion of less than 3ns at 5V operation. Designed with independent data channels, the isolators offer tight channel matching at 3.0ns maximum. Operating on either side of a 1.8V to 5V supply voltage, the isolators are compatible with lower voltage systems and enable voltage translation across the isolation barrier. Even in the absence of input logic transitions, DC correctness is ensured. The ADuM120N/ADuM121N Digital Isolators are qualified for automotive applications, and are available in a variety of configurations with a 3kVrms withstand voltage.
