Hi team,
What does Source off-capacitance and Drain off-capacitance mean? Does it mean the source and drain only have 2-4pF capacitance between them?
Is above paramater related to Off Isolation vs Frequency figure?
Thanks

Hi Jeff,
The on and off state capacitances stated in switch/mux datasheets are the shunt capacitance to ground (with CD for drain side, CS for source side)
Below is a video with more details on mux capacitances:
On the other hand, off isolation is defined as voltage at output pin of a multiplexer when a known signal is applied at the source pin of an off-channel:
VOUT = Voltage measured at source pin of off channel
VIN = Voltage applied at source pin of off channel
Below is another video with more detail information with off isolation:
Thank you,
Helen
