900MHz Multiplexing Amplifier
The ISL59441 is 900MHz bandwidth 4:1 multiplexing
amplifier designed primarily for video switching. This Mux
amp has a 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 ISL59441 to the low current power-down
mode for power sensitive applications - consuming just 5mW.

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.
