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.
