Multiplexing
Many systems, such as docking stations and memory banks,
have a large number of common bus signals. Common prob-
lems faced by designers of these systems include
Large delays caused by capacitive loading of the bus
Noise due to simultaneous switching of the address and data
bus signals
Figure 6 shows an array of memory banks in which each address
and data signal is loaded by the sum of the individual loads. If
a bus switch is used as shown in Figure 7, the output load on
the memory address and data bits is halved. The speed at which
the selected bank’s data can flow is much improved
because the capacitance loading is halved and the switches
introduce negligible propagation delay. Bus noise is also reduced.
