LT6556 - 750MHz Gain of 1 Triple 2:1Video Multiplexer

While the performance of the LT6556 is optimized for dual supply operation, it can also be operated with a single supply as low as 4.5V. Using dual 5V supplies, each amplifier draws only 9.5mA. When disabled, the amplifiers draw less than 330µA and the outputs become high impedance. For applications requiring a fi xed gain of 2, refer to the LT6555 datasheet.

The LT6556 is available in 24-lead SSOP and ultra-compact 24-lead QFN packages.
