Abstract
Circuitry may include a substrate with an input and an output circuit coupled in series at an intermediate node. The output circuit may have an output transistor and a stack transistor coupled in series between an output node and a voltage supply terminal. The two circuits may be placed on the substrate such that a single event transient charge injected into a sensitive diffusion of the intermediate node is shared through the substrate with the sensitive diffusion of the stack transistor of the output circuit. The charge sharing may reduce the recovery time at the output node and help to reduce the recovery time at the intermediate node, thereby providing increased single event transient robustness and reducing the probability of a permanent flip of the intermediate node and the output node of the circuitry.
