July 31, 2014 500MHz 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 unneeded circuitry in power sensitive
applications. When the ENABLE pin is pulled high, the part enters
a power-down mode and consumes just 14mW.
