... Data Sheet 500MHz Triple 2:1 Gain-of-2, Multiplexing Amplifier The ISL59448 is a triple channel 2:1 multiplexer featuring integrated buffers 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 ...
