Abstract
A bus driver circuit having an active low-side driver and a hybrid high-side driver. When driving a logic high, the bus driver circuit delivers an active 'kick' to pull the bus to a logic high state quickly and then releases the bus, allowing a weak pull-up resistor to maintain the voltage level of the bus for the remainder of the valid data phase. This kick is of limited duration, preferably lasting only long enough to bias the bus to a stable logic high while providing a remaining portion of the valid data phase that is of sufficient length for a contending bus agent to pull the bus low. The weak pull-up resistor is of sufficient size to reduce the chance that several resistors in parallel will prevent any active low-side driver of any bus agent from pulling the bus down to a low state.
