... Triple 4:1 Gain-of-2, Multiplexing Amplifier The ISL59446 is a triple channel 4:1 multiplexer featuring integrated amplifiers with a fixed gain of 2, high slew-rate and excellent bandwidth for video switching. The device features a three-state output (HIZ), which allows the outputs of multiple devices to be tied together. A power-down mode (ENABLE) is included to turn off un-needed circuitry in power sensitive applications ...

... GND SIGNAL DECOUPLING CAPS V- SUPPLY 11 ISL59446 HIZ State An internal pull-down resistor ensures the device will be active with no connection to the HIZ pin. The HIZ state is established within approximately 20ns (Figure 26) by placing a logic high (>2V) on the HIZ pin. If the HIZ state is selected, the output impedance is ~1000Ω (Figure 8). The supply current during this state is same as the active state ...

... 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 ISL59446 that is dissipating 0.5W in +50°C ambient. Pad area requirements should be evaluated on a case by case basis. ...
