DESCRIPTION:
Enhanced N channel FET with no inherent diode to Vcc
16:8 multiplexer function with zero delay
Ω bidirectional switches connect inputs to outputs
5Ω
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 SOIC and QSOP packages
The QS3390 provides a 16:8 multiplexer logic switch. The low ON
resistance (5Ω) of the QS3390 allows inputs to be connected to the outputs
without adding propagation delay and without generating additional ground
bounce noise.
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. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

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 ∆Icc.
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.
