NOTES
1
Temperature range is as follows: B Version: –40
°
C to +85
°
C.
2
Typical values are at 25
°
C, unless otherwise stated.
3
Guaranteed by design, not subject to production test.
4
The digital switch contributes no propagation delay other than the RC delay of the typical R
of the switch and the load capacitance when driven by an ideal voltage
source. Since the 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 digital 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.
5
Propagation delay matching between channels is calculated from the on resistance matching and load capacitance of 50 pF.
Specifications subject to change without notice.
