ISL59482 FN6209
Rev 4.00
Aug 8, 2014 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.
