DESCRIPTION:
The QS4A201 is a high-performance CMOS two-by-two analog cross
point switch. This device provides two sets of five high-speed CMOS
switches providing "cross point" connection between inputs and outputs.
The low ON resistance of the QS4A201 allows inputs to be connected to
outputs with low insertion loss and high bandwidth. TTL-compatible control
circuitry with “Break-Before-Make” feature prevents contention.
The QS4A201 with 1.3GHz bandwidth makes it ideal for high-perfor-
mance video signal switching, audio signal switching, and telecomm routing
applications. High performance and low power dissipation makes this
device ideal for battery operated and remote instrumentation applications.
The QS4A201 is offered in the QSOP package and 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 QS4A201 is characterized for operation at -40°C to +85°C.
