IDTQS4A205 HIGH-PERFORMANCE CMOS ANALOG FOUR-CHANNEL SPDT MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS IDTQS4A205 HIGH-PERFORMANCE CMOS ANALOG FOUR-CHANNEL SPDT MUX/DEMUX FEATURES: DESCRIPTION: Low ON resistance: rDS(ON) = 5 The QS4A205 is a high-performance CMOS analog Four-Channel Fast transition time: tTRAN = 6ns SPDT multiplexer/demultiplexer with individual enables. The low On- Wide bandwidth: 830MHz (-3dB point) resistance of the QS4A205 allows inputs to be connected to outputs with low Crosstalk: -115dB at 50KHz, -100dB at 5MHz, -66dB at 30MHz insertion loss and high bandwidth. TTL-compatible control circuitry with Off-isolation: -90dB at 50KHz, -60dB at 5MHz, -50dB at 30MHz Break-Before-Make feature prevents contention. Single 5V supply The QS4A205 with 830MHz bandwidth makes it ideal for high-perfor- Can be used as multiplexer or demultiplexer mance video signal switching, audio signal switching, and telecomm routing TTL-compatible control inputs applications. High performance and low power dissipation makes this Ultra-low quiescent current: 3A device ideal for battery operated and remote instrumentation applications. Available in QSOP package 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 APPLICATIONS: boards High-speed video signal switching/routing Reduced system noise due to less pin inductance resulting in lower HDTV-quality video signal routing ground bounce Audio signal switching/routing The QS4A205 is characterized for operation at -40C to +85C.
