FN7459.1
400MHz Multiplexing Amplifier
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.

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.
