IDTQS4A105

HIGH-PERFORMANCE CMOS

TWO CHANNEL 4PST SWITCH

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.
