QS3861QG8

IDTQS3861 HIGH-SPEED CMOS 10-BIT BUS SWITCH WITH FLOW-THROUGH PINOUT INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED CMOS 10-BIT BUS SWITCH WITH FLOW-THROUGH PINOUT DESCRIPTION: FEATURES: • • • • • IDTQS3861 The QS3861 provides a set of ten high-speed CMOS TTL-compatible bus switches. The low ON resistance (5Ω) of the QS3861 allows inputs to be connected without adding propagation delay and without generating additional ground bounce noise. The Bus Enable (BE) signal turns the switches on. The QS3861 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 ground bounce Undershoot clamp diodes on all switch and control inputs 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 A9 B9 BE 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 IDTQS3861 HIGH-SPEED CMOS 10-BIT BUS SWITCH WITH FLOW-THROUGH PINOUT 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 - QSOP Green Thin Shrink Small Outline Package - TSSOP Green 3861 High Speed CMOS 10-Bit Bus Switch with Flow-Through Pinout Datasheet Document History 01/25/13 Pg. 1, 5 Updated the Ordering Information by removing non green package version, the “IDT” notation and Adding Tape and Reel information.
