The QS4A205 is a high-performance CMOS analog Four-Channel
SPDT multiplexer/demultiplexer with individual enables. The low Onresistance 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
Low ON resistance: rDS(ON) = 5Ω
Ω
Fast transition time: tTRAN = 6ns
Wide bandwidth: 830MHz (-3dB point)
Crosstalk: -115dB at 50KHz, -100dB at 5MHz, -66dB at 30MHz
Off-isolation: -90dB at 50KHz, -60dB at 5MHz, -50dB at 30MHz
Single 5V supply
Can be used as multiplexer or demultiplexer
TTL-compatible control inputs
Ultra-low quiescent current: 3μA
