FN6208.3
Dual, 500MHz Triple, Multiplexing
Amplifiers
The ISL59481 contains two independent unity gain triple 4:1
MUX amplifiers that feature high slew rate and excellent
bandwidth for RGB video switching. Each RGB 4:1 MUX
contains 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 unused circuitry
in power sensitive applications. With both EN pins pulled
high, the ISL59481 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.
