The ISL59421 is a 865MHz bandwidth multiplexing amplifier designed primarily for video switching. This Mux amp has user-settable gain and also features a high speed threestate function to enable the output of multiple devices to be wired together. All logic inputs have pull-downs to ground and may be left floating. The ENABLE pin, when pulled high, sets the ISL59421 to the low current power-down mode for power sensitive applications - consuming just 5mW.
