Abstract
A pad driver method and apparatus is presented. The pad driver includes a dual path configuration. The dual path includes a first path and a second path. Both paths include a pre-driver. The first path and the second path communicate high voltage signals and low voltage signals. The pre-driver in the first path drives a pFET device. The pre-driver in the second path drives an nFET device. The pFET and nFET devices provide an output signal, which drives a pad. Each pre-driver further includes a first path and a second path. The first path in the pre-driver supports high voltage operation and the second path in the pre-driver supports low voltage operation.
