10-BIT BUS SWITCH
IDTQS3384
DESCRIPTION:
FEATURES:
The QS3384provides a setoftenhigh-speedCMOS,TTL-compatible
bus switches. The low ON resistance of QS3384 allows inputs to be
connectedtooutputswithoutaddingpropagationdelayandwithoutgener-
atingadditionalgroundbounce.Twobanks of5switches arecontrolledby
independentBus Enable (BE)signals.
• Enhanced N channel FET with no inherent diode to Vcc
• 5Ω bidirectional switches connect inputs to outputs
• Zero propagation delay, zero added ground bounce
• Undershoot clamp diodes on all switch and control inputs
• Two enables control five bits each
The QS3384 is characterized for operation at -40°C to +85°C.
• Available in SOIC, 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

NOTES:
1. For conditions shown as Min. or Max., use the appropriate values specified under DC Electrical Characteristics.
2. Per TTL-driven input (VIN = 3.4V, control inputs only). A and B pins do not contribute to ΔIcc.
3. 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.

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 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.
