Circuits for implementing gating logic in a self-timed integrated circuit. An integrated circuit includes a plurality of interconnected logic blocks, each including a logic circuit and an output circuit. Each output circuit has a data input coupled to an output of the logic circuit, a gating input, and a data output coupled to an output of the logic block. The output circuit is coupled to place a value on the data input onto the data output when the gating input has a first value and the output circuit receives tokens indicating valid new data on both the data input and the gating input of the output circuit. The output circuit is coupled to leave the data output unchanged when the gating input has a second value and the output circuit receives a token indicating valid new data on both the data and gating inputs of the output circuit.
