... All logic inputs have pull-downs to ground and may be left floating. The EN pin, when pulled high, sets the ISL59424 and ISL59445 in to low current mode - consuming just 15mW. An added feature in the ISL59424 is a latch enable function (LE) that allows independent logic control using a common logic bus ...

... Application Information General The ISL59424 and ISL59445 are triple 2:1 and 4:1 muxes that are ideal for the matrix element of high performance switchers and routers. The ISL59424 and ISL59445 are optimized to drive a 1.5pF in parallel with a 500Ω load. The capacitance can be split between the PCB capacitance an and external load capacitance ...

... Adequate thermal heat sinking of the parts is also required. Application Example Figure 21 illustrates the use of the ISL59445, two ISL84517 SPST switches and one NC7ST00P5X NAND gate to mux 3 different component video signals and one RGB video signal. The SPDT switches provide the sync signal for the ...

... A dedicated layer eliminates the need for individual thermal pad area. When a dedicated layer is not possible a 1” x 1” pad area is sufficient for the ISL59445 that is dissipating 0.5W in +50°C ambient. Pad area requirements should be evaluated on a case by case basis. ...
