1GHz Triple Multiplexing Amplifiers
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 EN 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 (LE) that allows
independent logic control using a common logic bus. When
LE is high the last logic state is preserved

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
