FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
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 telecomm routing
applications. Low power dissipation makes this device ideal for battery
operated and remote instrumentation applications.
The QS4A105 is offered in the QSOP package which has several
advantages over conventional packages such as PDIP and SOIC, includ-
ing:
• Reduced signal delays due to denser component packaging on circuit
boards
• Reduced system noise due to less pin inductance
The QS4A105 is characterized for operation at -40°C to +85°C.
