ISL59420
400MHz Multiplexing Amplifier
The ISL59420 is a 420MHz bandwidth 2:1 multiplexing amplifier designed primarily for video switching. This Mux-amp has user-settable gain and also feature 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 ISL59420 to the low current power-down mode for power sensitive applications - consuming just 5mW.
