Qui ckSw itch 16:8 Multiplexer FEATURES/BENEFITS DESCRIPTION Enhanced N channel FET with no inherent diode to Voc 16:8 multiplexer function with zero delay * 50 bidirectional switches connect inputs to outputs Zero propagation delay, zero ground bounce Low power CMOS proprietary technology TTL compatible control inputs Undershoot clamp diodes on all control and switch pins Direct bidirectional connection for mux, demux Q$32390 is 25Q version for low noise Available in 28-pin SOIC (SO) & QSOP APPLICATIONS * Video, audio, graphics switching, muxing * Hot-swapping, hot-docking (Application Note AN-13) * Voltage translation (5V to 3.3V; Application Note AN-11) The QS3390 and QS32390 provide a 16:8 multi- plexer logic switch. The low ON resistance (5Q) of the QS3390 allows inputs to be connected to the outputs without adding propagation delay and with- out generating additional ground bounce noise. The QS32390 adds an internal 250 resistor to reduce reflection noise in high-speed applications. The en- able 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 time constant for the switch alone is of the order of 0.25ns for QS3390 and 1.25ns for QS32390 for C, = 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/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. 5-22 QUALITY SEMICONDUCTOR, INC.
