Abstract

An isolation circuit, comprising a first transistor having a gate, a first source/drain terminal, and a second source/drain terminal, a first pad coupled to the gate of the first transistor, the first pad operable to receive an enable signal, a second pad coupled to the first source/drain of the first transistor, the second pad operable to receive a ground potential, a first fuse device coupling the second source/drain terminal to a node, a second fuse device coupling the node to the first pad, a third pad operable to receive a signal to be applied to at least one die, and a second transistor operable to selectively transfer the signal received at the third pad to the at least one die in response to a control signal provided by the node.
