400MHz Multiplexing Amplifier
The ISL59440 is a 400MHz bandwidth 4:1 multiplexing
amplifier designed primarily for video switching. This Mux-
amp 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.
