Description
Silicon Lab's family of digital isolators are CMOS devices that employ
an RF coupler to transmit digital information across an isolation
barrier. Very high speed operation at low power levels is achieved.
These parts are available in a 16-pin wide body SOIC package. Three
speed grade options (1, 10, 150 Mbps) are available and achieve
typical propagation delay of less than 10 ns.

... It is recommended that the enable inputs be connected to an external logic high or low level when the Si84xx is operating in noisy environments Connect (NC) replaces EN1 on Si8440/45. No Connect replaces EN2 on the Si8445. No Connects are not internally connected and can be left floating, tied to VDD, or tied to GND. 5. "Powered" state (P) is defined as 2.375 V < VDD < 5.5 V. ...

... RF Radiated Emissions The Si8440 family uses a RF carrier frequency of approximately 2.1 GHz. This will result in a small amount of radiated emissions at this frequency and its harmonics. The radiation is not from the IC chip but due to a small amount of RF energy driving the isolated ground planes which can act as a dipole antenna. ...

... Si8440/41/42/45 4.5. RF Immunity and Common Mode Transient Immunity The Si8440 family has very high common mode transient immunity while transmitting data. This is typically measured by applying a square pulse with very fast rise/fall times between the isolated grounds. Measurements show no failures kV/µs. During a high surge event the output may glitch low for up to 20–30 ns, but the output corrects immediately after the surge event ...
