It can be used for memory interleaving where two memory banks need to be addressed simultaneously. It can also be used as two 16-bit to 8-bit multiplexers or as one 32-bit to 16-bit multiplexer. SELn inputs control the data flow. TESTn inputs control either one or two ports connection. Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices. The QS316233 is characterized for operation at -40°C to +85°C.

This current applies to the control inputs only and represents the current required to switch internal capacitance at the specified frequency. The A and B inputs generate no significant AC or DC currents as they transition. This parameter is guaranteed but not production tested.

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. 4 IDTQS316233 HIGH-SPEED CMOS QUICKSWITCH 32:16 MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION IDTQS XXXXX Device Type XX 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 Thin Shrink Small Outline Package 316233 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
