Abstract
An optoisolator leadframe includes first and second spaced parallel rails. First and second tie bars extend perpendicularly from the rails and connect the rails to form a planar open frame. A first lead assembly has a pad extending therefrom and is mounted to the open frame in coplanar relation therewith. A second lead assembly has a pad extending therefrom and is rotatably mounted to the open frame to enable the second lead assembly to be rotated 180.degree. from an initial position coplanar with the open frame to a second position coplanar with the open frame. In the second position, the pad of the second lead assembly is in overlying alignment with the pad of the first lead assembly. A tab and notch arrangement is provided to limit the travel of the second lead assembly as it is rotated to the second position. The tab and notch arrangement ensures that a coplanar relationship between the first and second lead assemblies is achieved and secures the second lead assembly in the second position. A method for assembling an optoisolator using the leadframe is also disclosed.
