Specifications subject to change without notice.
Temperature range is as follows: B Version: –40∞C to +85∞C.
Typical values are at 25∞C, unless otherwise stated.
Guaranteed by design, not subject to production test.
The digital switch contributes no propagation delay other than the RC delay of the typical R
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.
Propagation delay matching between channels is calculated from the on resistance matching and load capacitance of 50 pF.
See Timing Measurement Information section.
This current applies to the control pin BE only. The A and B ports contribute no significant ac or dc currents as they transition.
