ISL59440 400MHz Multiplexing Amplifier The ISL59440 is a 400MHz bandwidth 4:1 multiplexing amplifier designed primarily for video switching.
This Muxamp has user-settable gain and also features a high speed three-state 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 ISL59440 to the low current power-down mode for power sensitive applications - consuming just 5mW.
