Abstract
Preventing transistor damage to an integrated circuit is described. The circuit includes a switch with a first pair of p-type transistors respectively coupled in source-drain parallel with second pair of p-type transistors for preventing Negative Bias Temperature Instability ('NBTI') damage to the second pair of p-type transistors. The switch is configured to such that when in a state associated with causing, or potentially causing, NBTI damage, both of the second pair of p-type transistors are in an OFF state for preventing NBTI damage thereto.
