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-performance 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 advantages 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.
