... IN 50Ω Application Information General The ISL59440 is a 4:1 mux that is ideal as a matrix element in high performance switchers and routers. The ISL59440 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 provides excellent 50Ω ...

... GND SIGNAL DE-COUPLING CAPS V- SUPPLY 10 ISL59440 HIZ State An internal pull-down resistor connected to the HIZ pin ensures the device will be active with no connection to the HIZ pin. The HIZ state is established within approximately 30ns (Figure 18) by placing a logic high (> 2V) on the HIZ pin. If the HIZ state is selected, the output is a high impedance 1.4MΩ ...

... When vias are required in a layout, they should be routed as far away from the device as possible. • The NIC pins are placed on both sides of the input pins. These pins are not internally connected to the die recommended these pins be tied to ground to minimize crosstalk. 11 ISL59440 FN6162.1 September 21, 2005 ...
