Description
The AS131-59 is a high isolation IC FET SPDT
non-reflective switch in a plastic MSOP-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
telecommunications applications.
