descriptionThe LT®6556 is a high speed triple 2:1 video multiplexer with an internally fixed gain of 1.®The LT 6556 is a high speed triple 2:1 video multiplexer with an internal 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.A 1k load and features 2VP-P's -3dB bandwidth of 450MHz, individual buffer performance optimization, making them ideal for driving very high definition 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.Each amplifier UH boost channel separates a separate 72dB supply supply pin, enabling the LT6556 to be used in Excel at many high speeds.

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.Although the LT6556 is optimized for performance, it operates from dual supplies and can also be operated as a single supply as low as 4.5V. Using dual 5V supplies, each amplifier draws only 9.5mA.Using dual 5V supplies, each amplifier draws only 9.5 mA. When disabled, the amplifiers draw less than 330µA and the outputs become high impedance.When disabled, the amplifier plots less than 330μA and the output becomes high impedance. For applications requiring a fi xed gain of 2, refer to the LT6555 datasheet.For applications requiring 2 fixed gains of Fi, data is available on the LT6555.

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