Digital isolators with
isolation in designs without the cost, size, power, performance, and reliabil-
ity constraints found with optocouplers. Coupler digital isolators also meet
the wide range of creepage/clearance requirements and are the industry’s
only digital isolators with certified 8 mm creepage. With more than half a
billion channels shipped into the field, these magnetically isolated products
meet the same rigid safety standards as optocouplers.
