Abstract
Disclosed embodiments are directed to an electrical overstress protection circuit. The electrical overstress protection circuit may include an intermediate node receiving a reference voltage, a first pair of clamp devices, having opposite polarity, clamping an input signal line to the intermediate node, and a second pair of clamp devices, each clamping the intermediate node to one of two reference potentials. The electrical overstress protection circuit may also include a filter connected to the intermediate node to reduce noise at the intermediate node.
