ISL59483
FN6394.2
Dual, 500MHz Triple, Multiplexing
Amplifiers
The ISL59483 contains a gain of 1 triple 4:1 MUX amplifier
(MUX1), and a second gain of 2 triple 4:1 MUX amplifier
(MUX2). Each feature high slew rate and excellent
bandwidth for RGB video switching. They contain separate
binary coded, channel select logic inputs (S0, S1), and
separate logic inputs for High Impedance output (HIZ) and
power-down (EN) modes. The HIZ state presents a high
impedance at the output so that both RGB MUX outputs can
be wired together to form an 8:1 RGB MUX amplifier or they
can be used in R-R, G-G, and B-B pairs to form a 4:1
differential input/output MUX. Separate power-down mode
controls (EN1, EN2) are included to turn off unneeded
circuitry in power sensitive applications. With both EN pins
pulled high, the ISL59483 enters a standby power mode,
consuming just 36mW.

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.
