DIGITAL SWITCH
Temperature range is: B Version: –40°C to +85°C.
See Test Circuits and Waveforms.
All typical values are at T
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 ON resistance matching of worst-case channel combinations and load capacitance.
This current applies to the control pins only and represents the current required to switch internal capacitance at the specified frequency. The A and B ports
contribute no significant ac or dc currents as they transition. This parameter is guaranteed by design, not subject to production test.
