QS4A105 Overview
The QS4A105 is a high-performance CMOS two-channel 4PST switch with 3-state outputs. The low ON resistance of the QS4A105 allows inputs to be connected to outputs with low insertion loss and high bandwidth. The QS4A105, with 1.3GHz bandwidth, is ideal for high-performance video signal switching, audio signal switching, and telem routing applications.
