Temperature range is as follows for B Version: −40°C to +85°C.
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 resistance-capacitance (RC) delay of the typical R
ON
of the switch and the load capacitance when
driven by an ideal voltage source. Because 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.
