FN7452.2
1GHz, 4 x 1 Multiplexing Amplifier
The ISL59442 is a single-output 4:1 MUX-amp. The
MUX-amp has a fixed gain of 1 and a 1GHz bandwidth. The
device contains logic inputs for channel selection (S0, S1),
and a three-state output control (HIZ) for individual
selection of MUX amps that share a common video output
line. All logic inputs have pull-downs to ground and may be
left floating.

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.
