1 Temperature range is as follows for 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 resistance-capacitance (RC) delay of the typical RON 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.
