865MHz Multiplexing Amplifier
The ISL59421 is a 865MHz bandwidth multiplexing amplifier
designed primarily for video switching. This Mux amp has
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 ISL59421 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.
