400MHz Multiplexing Amplifier
ISL59420
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.
