IDTQS32X245 HIGH-SPEED CMOS QUICKSWITCH DOUBLE-WIDTH BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS QUICKSWITCH DOUBLE-WIDTH BUS SWITCH DESCRIPTION: FEATURES: • • • • • • • IDTQS32X245 The QS32X245 provides a set of 16 high-speed CMOS TTL-compatible bus switches in a flow-through pinout. The low ON resistance of the QS32X245 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The Output Enable (OEn) signals turn the switches on similar to the OEn signal of the 74'245. QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices. The QS32X245 is characterized for operation at -40°C to +85°C. Enhanced N channel FET with no inherent diode to Vcc Ω bidirectional switches connect inputs to outputs 5Ω Dual '245 function Zero propagation delay, zero ground bounce Undershoot clamp diodes on all switch and control inputs TTL-compatible control inputs Available in 40-pin QVSOP package APPLICATIONS: • • • • • • Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Bus switching and isolation Power conservation Clock gating Logic replacement FUNCTIONAL BLOCK DIAGRAM A0 A1 A2 A3 A4 A5 A6 A7 B0 B1 B2 B3 B4 B5 B6 B7 A8 A9 A10 A11 A12 A13 A14 A15 B8 B9 B10 B11 B12 B13 B14 B15 OE1 OE2 IDT and the IDT logo registered trademarks of Integrated Device Technology, Inc.

Unit — — 0.25 ns 0.5 — 5.6 ns 0.5 — 4.5 ns NOTES: 1. 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 for 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 IDTQS32X245 HIGH-SPEED CMOS QUICKSWITCH DOUBLE-WIDTH BUS SWITCH INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION QS XXXXX Device Type XX Package X Process X Blank 8 Tube or Tray Tape and Reel Blank Industrial (-40°C to +85°C) Q2G 40-Pin QVSOP - Green 32X245 High Speed CMOS QuickSwitch Double Width Bus Switch Datasheet Document History 01/08/09 Pg. 5 02/16/11 Pg. 5 Updated the ordering information by removing the "IDT" notation and non RoHS part.
