A dynamic logic circuit (30). The dynamic logic circuit comprises a precharge node (30PN) to be precharged to a precharge voltage (VDD) during a precharge phase and a conditional discharge path (30L, 30DT) connected to the precharge node. The conditional discharge path is operable, during an evaluate phase, to conditionally couple the precharge node to a voltage different than the precharge voltage. The dynamic logic circuit also comprises an output (OUT3) for providing a signal in response to a state at the precharge node. Lastly, the dynamic logic circuit comprises voltage maintaining circuitry (30KT1, 30KT2), coupled to the output, for coupling the precharge voltage to the precharge node during a portion of an instance of the evaluate phase when the conditional discharge path is not enabled during the instance of the evaluate phase. <IMAGE>
