LT6555 - 650MHz Gain of 2 Triple 2:1Video Multiplexer

While the performance of the LT6555 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 9mA. When disabled, the amplifiers draw less than 500µA and the outputs become high impedance.

The LT6555 is manufactured on Linear Technology's proprietary low voltage complementary bipolar process and is available in 24-lead SSOP and ultra-compact 24-lead QFN packages.
