... IN 50Ω Application Information General The ISL59420 is a 2:1 mux that is ideal as a matrix element in high performance switchers and routers. The ISL59420 is optimized to drive 5pF in parallel with a 500Ω load. The capacitance can be split between the PCB capacitance and an external load capacitance. Its low input capacitance and high input resistance provide excellent 50Ω ...

... SIGNAL DE-COUPLING CAPS V- SUPPLY 10 ISL59420 connected to V+, can result in damaging currents through the ESD diodes and other active circuits within the device. Therefore, adequate current limiting on the digital and analog inputs is needed to prevent damage during the time the voltages on these inputs are more positive than V+. ...

... Avoid vias between the cap and the device because vias add unwanted inductance. Larger caps can be farther away. When vias are required in a layout, they should be routed as far away from the device as possible. 11 ISL59420 FN7459.1 September 22, 2005 ...
