IDTQS3384 HIGH-SPEED CMOS 10-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS 10-BIT BUS SWITCH DESCRIPTION: FEATURES: • • • • • • IDTQS3384 The QS3384 provides a set of ten high-speed CMOS, TTL-compatible bus switches. The low ON resistance of QS3384 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce. Two banks of 5 switches are controlled by independent Bus Enable (BE) signals. The QS3384 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 Zero propagation delay, zero added ground bounce Undershoot clamp diodes on all switch and control inputs Two enables control five bits each Available in QSOP and TSSOP packages APPLICATIONS: • • • • • • Hot-swapping, hot-docking Voltage translation (5V to 3.3V) Power Conservation Capacitance reduction and isloation Bus Isolation Clock Gating FUNCTIONAL BLOCK DIAGRAM A0 B0 A4 B4 A5 B5 A9 B9 BEA BEB The IDT logo is a registered trademark of Integrated Device Technology, Inc.

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 IDTQS3384 HIGH-SPEED CMOS 10-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE ORDERING INFORMATION QS XXXXX Device Type XX Package X Blank 8 Tube or Tray Tape and Reel QG PAG Quarter Size Outline Package - Green Thin Small Size Outline Package - Green 3384 High Speed CMOS 10-Bit Bus Switch Datasheet Document History 10/25/11 Pg. 5 Updated ordering information to include tube or tray and tape & reel.
