Selectors can be connected to a single date bus as shown.
One MC14512B is selected by the 3−state control, and the
remaining devices are disabled into a high−impedance “off”
state. The number of 8−bit data selectors, N, that may be
connected to a bus line is determined from the output drive
current, I
and the load current, I
