The QS4A110 is a high-performance CMOS two-channel 5PST switch
with 3-state outputs. The low ON resistance of the QS4A110 allows inputs
to be connected to outputs with low insertion loss and high bandwidth.
The QS4A110, with 1.8GHz 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 QS4A110 is offered in the QSOP package which has several
advantages over conventional packages such as PDIP and SOIC, including:
• Reduced signal delays due to denser component packaging on circuit
boards
• Reduced system noise due to less pin inductance

Low ON resistance: rDS(ON) = 5Ω
Ω
Wide bandwidth: 1.8GHz (-3dB point)
