ABSTRACT:
A driver circuit provides for selectively changing the state of an output signal, such as a pre-charged dynamic bus signal. The circuit detects whether or not the data is the opposite state as the pre-charged bus signal, and if so, it drives the bus to the appropriate state. The output from the circuit is self-timed when data can be driven onto the bus as soon as data is valid, i.e., data propagates from the input of the circuit to the bus without depending on a clock or other timing edge.
