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.
