A bus-holder or bus-keeper is a weak latch circuit that holds the last value on a tri-state bus. The circuit is basically a delay element with the output connected back to the input through a relatively high impedance. This is usually achieved with two inverters connected in series, followed by a series resistor connected to the second inverter. The resistor drives the bus weakly; therefore other circuits can override the value of the bus when they are not in tri-state mode. Bus-holders are used
