Extended voltage range coldspare tolerant off chip driver
An off chip driver circuit includes a bias circuit and a driver sub-cell circuit. The bias circuit and off chip driver sub-cell circuit are in electrical communication with each other. The bias circuit includes two serially aligned diodes which are in an off-state when the driver sub-cell is in a functional mode and which are in an on-state when the driver sub-cell is in a cold spare mode. The arrangement of the diodes enables the off chip driver circuit to handle similar voltage signals in both the functional mode and the cold spare mode.
