Description
The AS338-12 is a low-cost IC FET SPDT nonreflective switch in
a plastic SOIC-8 package for commercial applications. The switch
operates with -5, 0 V or 0, +5 V when “floated” as shown on the
following page. This general-purpose SPDT switch is used in var-
ious telecommunications applications.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
