6-Channel 4:1 Analog Mux/Demux

The QS4A215 is a high-performance CMOS six-channel multiplexer/ demultiplexer with individual enables. The low ON-resistance of the QS4A215 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 QS4A215 with 700MHz bandwidth makes it ideal for high-performance video signal switching, audio signal switching, and telecom routing applications. High performance and low power dissipation makes this device ideal for battery operated and remote instrumentation applications. The QS4A215 is offered in the QVSOP package which 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 QS4A215 is characterized for operation at -40°C to +85°C.
