The QS4A210 is a high-performance CMOS two-channel SP4T multiplexer/demultiplexer with individual enables. The low On-resistance of the
QS4A210 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 QS4A210 with 700MHz bandwidth makes it ideal for high-performance video signal switching, audio signal switching, and telecom routing
applications. Low power dissipation makes this device ideal for battery
operated and remote instrumentation applications.
The QS4A210 is offered in the QSOP 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
Low ON resistance: rDS(ON) = 5Ω
Ω
Fast transition time: tTRAN = 6ns
