Another chip to look at is the 74HC251. Two of these 8->1 multiplexers and 4 output control lines plus 1 input line would allow you to monitor any one input of the 10 in real time after the input was selected via the outputs. One of the 4 output control lines would need an inverter or a transistor to provide true and complement signals to drive the two output controls of the HC251.
