SWITCHING CHARACTERISTICS OVER OPERATING RANGE
Commercial: T
A = –40°C to 85°C, VCC = 5.0V ±5%
Military: T
A = –55°C to 125°C, VCC = 5.0V ±10%
C
LOAD = 50pF, RLOAD = 500 unless otherwise noted.
Notes:
1. See Test Circuit and Waveforms. Minimums guaranteed but not production tested.
2. This parameter is guaranteed by but not production tested.
3. The time constant for the switch alone is of the order of 0.25ns for QS3384 and 1.25ns for QS3284 for C
L = 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 system is determined by
the driving circuit on the driving side of the switch and its interaction with the load on the driven side.
Notes:
1. For conditions shown as Min. or Max., use the appropriate values specified under DC specifications.
2. Per TTL driven input (V
IN = 3.4V, control inputs only). A and B 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 and B inputs generate no
significant AC or DC currents as they transition. This parameter is guaranteed by characterization, but not production tested.
