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
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.

See Timing Measurement Information section.
6
This current applies to the Control Pin
BE
only. The A and B ports contribute no significant ac or dc currents as they transition.
