NOTES
1Temperature range is as follows: B Version: –40
∞C to +85∞C.
2Typical values are at 25
∞C, unless otherwise stated.
3Guaranteed by design, not subject to production test.
4The digital switch contributes no propagation delay other than the RC delay of the typical R
ON 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.
5Propagation delay matching between channels is calculated from the on resistance matching and load capacitance of 50 pF.
6See Timing Measurement Information section.
7This current applies to the control pins (
BEx) only. The A and B ports contribute no significant ac or dc currents as they transition.
