ISL59424, ISL59445
1GHz Triple Multiplexing Amplifiers
The ISL59424, ISL59445 are 1GHz bandwidth multiplexing
amplifiers designed primarily for video input switching.
These MUX-amps exhibit a fixed gain of 1 and also feature a
high speed three-state 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 EN pin, when pulled
high, sets the ISL59424, ISL59445 in to low current
mode-consuming just 15mW. An added feature in the
ISL59424 is a latch enable function (LE) that allows
independent logic control using a common logic bus. When
LE is high the last logic state is preserved
.
