The ISL59424 and 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 span style="text-decorati
on: overline"EN/span pin, when pulled high, sets the ISL59424 and ISL59445 in to low current mode - consuming just 15mW. An added feature in the ISL59424 is a latch enable function (span style="text-decorati
on: overline"LE/span) that allows independent logic control using a common logic bus. When span style="text-decorati
on: overline"LE/span is high the last logic state is preserved.brbr
