IDTQS4A101

HIGH-PERFORMANCE CMOS ANALOG

FOUR-CHANNEL SPST SWITCH

WITH INDIVIDUAL ENABLES

DESCRIPTION:

The QS4A101 is a high-performance CMOS analog four-channel SPST

switch with individual enables. This device provides a set of four high-speed

CMOS switches connecting inputs to outputs. The low ON resistance of the

QS4A101 allows inputs to be connected to outputs with low insertion loss and

high bandwidth.

The QS4A101, with 1.4GHz 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 QS4A101 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 QS4A101 is characterized for operation at -40°C to +85°C.
