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

The LT®6556 is a high speed triple 2:1 video multiplexer with an internally fixed gain of 1. The individual buffers are optimized for performance with a 1k load and feature a 2VP-P -3dB bandwidth of 450MHz, making them ideal for driving very high resolution video signals. Separate power supply pins for each amplifi er boost channel separation to 72dB, allowing the LT6556 to excel in many high speed applications.

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
