Patent ID: 7652507

Claim:
A device comprising: a wire for propagating a signal; a circuit coupled to the wire, the circuit having an input and an output, the circuit causing a first transistor to turn on and then turn off, the first transistor driving the output to a first state in response to the circuit detecting a first transition in the signal, the circuit comprising a delay chain coupled between the input and the output and operable for maintaining the first state at the output with the first transistor turned off until a second transition is detected in the signal, wherein in response to the circuit detecting the second transition the circuit causes a second transistor that is coupled to the output to turn on and then turn off, the second transistor driving the output to a second state, and the circuit maintaining the second state at the output with the second transistor turned off until a third transition is detected in the signal; the circuit further comprising first circuitry coupled to the input, the first circuitry causing the second transistor to turn on during the second transition and then turn off after a first period of time, the second transistor driving the output to the second state to assist in the second transition.
