ISL59444
FN7451.1
1GHz, 4 x 1 Multiplexing Amplifier with
Synchronous Controls
The ISL59444 is a single-output 4:1 MUX-amp. The MUX-amp
has a fixed gain of 1 and a 1GHz bandwidth. The ISL59444 is
ideal for professional video switching, HDTV, computer
display routing, and other high performance applications.
The device contains logic inputs for channel selection (S0,
S1), latch control signals (LE1, LE2), 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.
