Description
The AS338-12 is a low cost IC FET SPDT non-reflective
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 various tele-
communications applications.
