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
Undershoot clamp diodes on all switch and control inputs
Direct bidirectional connection for mux, demux
Ω resistors for low noise
25Ω
Available in QSOP package
The QS32390 provides a 16:8 multiplexer logic switch. The QS32390 has
an internal 25Ω resistor to reduce reflection noise in high-speed applications. The enable inputs connect one of two inputs to the common I/O pin,
respectively. The multiplexer function can be used to select and route logic
signals for zero delay, isolate bus capacitance, form crossbar switches, etc.
Mux/Demux devices provide an order of magnitude faster speed than
equivalent logic devices.
The QS32390 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)

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.

2. Per TLL 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 I/Os 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 time constant for the switch alone is of the order of 1.25ns for CL = 50pF.
4. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. 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.
