Notes:
1. See Test Circuit and Waveforms. Mnimums 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 QS32XL384 and 1.25ns for QS32XL2384 for C
= 50pF.
4. 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/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 systemis determned by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.
5. Measured at switch turn off, A to B, load = 50pF in parallel with 10 Meg scope probe, V

at A = 0.0V.

Notes:
1. For conditions shown as Mn. or Max., use the appropriate values specified under DC specifications.
2. Per TTL driven input (V
= 3.4V, control inputs only). A and B pins do not contribute to
I
.
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.
