APPLICATIONS INFORMATION
Figure
Multiplexer/Demultiplexer. The 0–to–5 volt Digital Control
signal is used to directly control a 5 V
p–p
analog signal.
The digital control logic levels are determined by V
DD
and V
SS
. The V
DD
voltage is the logic high voltage; the V
SS
voltage is logic low. For the example. V
DD
= + 5 V = logic
high at the control inputs; V
SS
= GND = 0 V = logic low.
The maximum analog signal level is determined by V
DD
and V
SS
. The analog voltage must swing neither higher than
V
DD
nor lower than V
SS
. The example shows a 5 V
p–p
A
illustrates
use
of
the
Analog
signal which allows no margin at either peak. If voltage
transients above V
DD
and/or below V
SS
are anticipated on
the analog channels, external diodes (D
x
) are recommended
as shown in Figure B. These diodes should be small signal
types able to absorb the maximum anticipated current surges
during clipping.
The absolute maximum potential difference between V
DD
and V
SS
is 18.0 volts. Most parameters are specified up to
15 V which is the recommended maximum difference
between V
DD
and V
SS
.
