ABSTRACT:
An apparatus includes a single-rail input connected to a low-voltage domain and a voltage-transition circuit connected to the single-rail input. The voltage-transition circuit is configured to convert a voltage of the low-voltage domain received via the single-rail input to a voltage of the high-voltage domain.
