IDTQS32390 HIGH-SPEED CMOS QUICKSWITCH 16:8 MULTIPLEXER INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUICKSWITCH 16:8 MULTIPLEXER FEATURES: • • • • • • • • IDTQS32390 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) FUNCTIONAL BLOCK DIAGRAM A0 AB0 A7 AB7 AEN B0 B7 BEN The IDT logo is a registered trademark of Integrated Device Technology, Inc.

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.

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. 4 IDTQS32390 HIGH-SPEED CMOS QUICKSWITCH 16:8 MULTIPLEXER INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION IDTQS XXXXX Device Type XX Package Q QG Quarter Size Outline Package QSOP - Green 32390 High Speed CMOS QuickSwitch 16:8 Multiplexer As per PCN L0201-02, the Output Resistance (RON) specifications have changed as of March 8, 2002.
