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. |
