... Data Sheet Dual, 500MHz Triple, Multiplexing Amplifiers The ISL59482 contains two independent fixed gain of 2 triple 4:1 MUX amplifiers that feature high slew rate and excellent bandwidth for RGB video switching. Each RGB 4:1 MUX contains binary coded, channel select logic inputs (S0, S1), and separate logic inputs for High Impedance Output (HIZ) and power-down (EN) modes ...

... Application Information General The ISL59482 is ideal as the matrix element of high performance switchers and routers. Key features include internal fixed gain of 2, high impedance buffered analog inputs and excellent AC performance at output loads down to 150Ω for video cable-driving. The current feedback output amplifiers are stable operating into capacitive loads ...

... PC board. In cases where a dedicated layer is not possible, AC performance may be reduced at upper frequencies. 12 ISL59482 The thermal pad requirements are proportional to power dissipation and ambient temperature. A dedicated layer eliminates the need for individual thermal pad area. When a dedicated layer is not possible, an isolated thermal pad on another layer should be used ...
