... Data Sheet 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 ...
