Overview

Description

The QS4A105 is a high-performance CMOS two-channel 4PST switch with 3-state outputs. The QS4A105, with 1.3GHz bandwidth, is ideal for high-performance video signal switching, audio signal switching, and telecomm routing applications. Low power dissipation makes this device ideal for battery operated and remote instrumentation applications. The QS4A105 operates at -40C to +85C.
