HIGH-SPEED CMOS QUICKSWITCH
16:8 MULTIPLEXER
FEATURES:
DESCRIPTION:
• Enhanced N channel FET with no inherent diode to Vcc
• 16:8 multiplexer function with zero delay
The QS3390 provides a 16:8 multiplexer logic switch. The low ON
resistance(5Ω)oftheQS3390allowsinputstobeconnectedtotheoutputs
withoutaddingpropagationdelayandwithoutgeneratingadditionalground
bounce noise.
• 5Ω bidirectional switches connect inputs to outputs
• Zero propagation delay, zero ground bounce
• Low power CMOS proprietary technology
• Undershoot clamp diodes on all switch and control inputs
• Direct bidirectional connection for mux, demux
• Available in QSOP package
Mux/Demux devices provide an order of magnitude faster speed than
equivalent logic devices.
The QS3390 is characterized for operation at -40°C to +85°C.
APPLICATIONS:
• Video, audio, graphics switching, muxing
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)

NOTES:
1. For conditions shown as Min. or Max., use the appropriate values specified under DC Electrical Characteristics.
2. Per TTL-driven input (VIN = 3.4V, control inputs only). A, B, and AB pins do not contribute to ΔIcc.
3. This current applies to the control inputs only and represents the current required to switch internal capacitance at the specified frequency. The A, B, and AB inputs generate
no significant AC or DC currents as they transition. This parameter is guaranteed but not production tested.

NOTES:
1. Minimums are guaranteed but not production tested.
2. This parameter is guaranteed but not production tested.
3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone
is of the order of 0.25ns at CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the
system. Propagation delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on
the driven side.
