ISL59482

Dual, 500MHz Triple, Multiplexing

Amplifiers

The ISL59482 contains two independent fixed gain of 2 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 unneeded

circuitry in power sensitive applications. With both EN pins

pulled high, the ISL59482 enters a standby power mode-

consuming just 34mW.

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.
