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 un-needed circuitry in power
sensitive applications. When the ENABLE pin is pulled high,
the part enters a power-down mode and consumes just
14mW.
