______________________________________________________________________________________
The most straightforward technique for implementing
nonblocking matrices is to arrange the building blocks
in a grid. The inputs connect to each vertical bank of
devices in parallel with the other banks. The outputs of
each building block in a vertical column connect
together in a wired-OR configuration. Figure 6.shows a
128-input, 32-output, nonblocking array using eight
MAX4358 crosspoint devices.
The wire-OR connection of the outputs shown in the
diagram is possible because the outputs of the IC
devices can be placed in a disabled, or high-imped-
ance-output state. This disable state of the output
buffers is designed for a maximum impedance vs. fre-
quency while maintaining a low output capacitance.
These characteristics minimize the adverse loading
effects from the disabled outputs. Larger arrays are
constructed by extending this connection technique to
more devices.
Driving a Capacitive Load
Figure 6 shows an implementation requiring many out-
puts to be wired together. This creates a situation
where each output buffer sees not only the normal load
impedance, but also the disabled impedance of all the
other outputs. This impedance has a resistive and a
capacitive component. The resistive components
reduce the total effective load for the driving output.
