Analog Devices Inc. ADuM141D/E Quad-Channel Digital Isolators

Analog Devices ADuM141D/E Automotive-Qualified Quad-Channel Digital Isolators offer a maximum 13ns propagation delay and less than 3ns pulse width distortion (PWD) at 5V operation. The isolators provide high 100kV/µs common-mode transient immunity and tight channel matching at 3.0ns maximum. The isolators’ data channels are independent and available in a variety of configurations. The data channels have a 150Mbps maximum data rate and a 3.0kVRMS or 3.75kVRMS withstand voltage rating.

The ADuM141D/E isolators operate on either side of a supply voltage ranging from 1.8V to 5V. The capability to operate on either side of the supply voltage enables voltage translation functionality across the isolation barrier and compatibility with lower voltage systems.

Based on iCoupler® technology, the ADuM141D/E isolators ensure DC correctness in the absence of input logic transitions. The isolators feature two different fail-safe options. The fail-safe options allow the outputs to transition to a predetermined state when the input power supply is not applied or the inputs are disabled.
