IDTQS3L383
HIGH-SPEED LOW POWER
10-BIT BUS EXCHANGE SWITCH
DESCRIPTION:
FEATURES:
−
−
−
−
−
−
−
Enhanced N channel FET with no inherent diode to Vcc
5Ω bidirectional switches connect inputs to outputs
Zero propagation delay, zero ground bounce
Ultra low power with 0.2µA typical ICC
Undershoot clamp diodes on all switch and control pins
Bus exchange allows nibble swap
The QS3L383 provides ten high-speed CMOS TTL-compatible bus
switches. The low ON resistance of the QS3L383 allows inputs to be
connectedtooutputswithoutaddingpropagationdelayandwithoutgener-
atingadditionalgroundbounce noise. The Bus Enable (BE)signalturns
the switches on. The Bus Exchange (BX) signal provides nibble swap of
the AB and CD pairs of signals. This exchange configuration allows byte
swapping of buses in systems. It can also be used as a 5-wide 2-to-1
multiplexerandtocreate lowdelaybarrelshifters,etc.
Available in SOIC and QSOP Packages
APPLICATIONS
The QS3L383 is characterized for operation at -40°C to +85°C.

2. Per TLL driven input (VIN = 3.4V, control inputs only). A, B, C, and D pins do not contribute to ∆Icc

3. This current applies to the control inputs only and represents the current required to switch internal capacitance at the specified frequency. The A,
B, C, and D 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 time constant for the switch alone is of the order of 0.25ns for CL = 50pF. The bus switch contributes no propagation delay other than the RC
delay of the ON resistance of the switch and the load capacitance. 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.
