DESCRIPTION:
The QS4A205 is a high-performance CMOS analog Four-Channel
SPDT multiplexer/demultiplexer with individual enables. The low On-
resistance of the QS4A205 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 QS4A205 with 830MHz 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 QS4A205 is offered in the QSOP package and has several advan-
tages 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 resulting in lower
ground bounce
The QS4A205 is characterized for operation at -40°C to +85°C.
