APPLICATIONS INFORMATION
Figure A illustrates use of the Analog Multiplexer/Demulti-
plexer. The 0–to–5 volt Digital Control signal is used to
directly control a 5 Vp–p analog signal.
The digital control logic levels are determined by VDD and
VSS. The VDD voltage is the logic high voltage; the VSS volt-
age is logic low. For the example. VDD = + 5 V = logic high at
the control inputs; VSS = GND = 0 V = logic low.
The maximum analog signal level is determined by VDD
and VSS. The analog voltage must swing neither higher than
VDD nor lower than VSS. The example shows a 5 Vp–p signal
which allows no margin at either peak. If voltage transients
above VDD and/or below VSS are anticipated on the analog
channels, external diodes (Dx) 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 VDD
and VSS is 18.0 volts. Most parameters are specified up to
15 V which is the recommended maximum difference
between VDD and VSS.
