Abstract
A circuit selects a highest priority signal from a plurality of input signals. The circuit comprises the following components. A plurality of serially coupled input blocks, each of which are coupled to a corresponding one of a plurality of input lines for receiving respective ones of the input signals and providing corresponding output signals. A pre-charging device coupled between a first supply voltage terminal and a first one of the serially coupled input blocks. The pre-charging device couples the supply voltage to the first one of the serially coupled input blocks in response to a clock pulse signal transition. An activation device coupled between a second supply voltage terminal and a last one of the serially coupled input blocks. The activation device couples the second supply voltage to the last one of the serially coupled input blocks in response to an activation signal transition.
