Application Notes
RFin3
1. ESD sensitive device observe handling precoution
2. Precaution should be taken to avoid the video
transients during switching period
VCTRL3
3. The device should be properly grounded to insure
the isolation performance
RFin4
4.Connected 4 input ports together can be functioned
as a multi throw switches Connected 4 input as outputs
can be functioned as a multi throw switches
