IDTQS3162233 HIGH-SPEED CMOS QUICKSWITCH 32:16 MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUICKSWITCH 32:16 MUX/DEMUX DESCRIPTION: FEATURES: − − − − − Enhanced N channel FET with no inherent diode to Vcc Zero propagation delay, zero ground bounce TTL-compatible input and output levels Undershoot clamp diodes on all switch and control pins Available in 56-pin SSOP and TSSOP Packages The QS3162233 is a 32-bit to 16-bit high-speed CMOS, TTL-compatible switch which can multiplex or demultiplex data. It can be used for memory interleaving where two memory banks need to be addressed simultaniously. It can also be used as two 16-bit to 8-bit multiplexers or as one 32-bit to 16bit multiplexer. SELn inputs control the data flow. TESTn inputs control either one or two ports connection. The QS3162233 adds an internal 25Ω series termination resistor to each switch to reduce reflection noise in high-speed applications. APPLICATIONS − − − − IDTQS3162233 Video, audio, graphics switching, muxing Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Bus funneling 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 1.25ns at 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 IDTQS3162233 HIGH-SPEED CMOS QUICKSWITCH 32:16 MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION IDTQS XXXXX XX Device Type Package X Process CORPORATE HEADQUARTERS 2975 Stender Way Santa Clara, CA 95054 Blank Industrial (-40°C to +85°C) PV PA Shrink Small Outline Package (SO56-1) Thin Shrink Small Outline Package (SO56-2) 3162233 High Speed CMOS QuickSwitch 32:16 Mux/Demux for SALES: 800-345-7015 or 408-727-6116 fax: 408-492-8674 www.idt.com 5 for Tech Support: [email protected] (408) 654-6459
