描述The LT®6556 is a high speed triple 2:1 video multiplexer with an internally fixed gain of 1.LT®6556是高速三重2:1与内部固定增益为1的视频复用器。 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.一个1k负载和功能2VP-P的-3dB带宽为450MHz，个别缓冲区性能优化，使他们驾驶非常高清晰度视频信号的理想选择。 Separate power supply pins for each amplifi er boost channel separation to 72dB, allowing the LT6556 to excel in many high speed applications.每个放大器呃升压型通道分离72分贝单独的电源供电引脚，使LT6556在许多高速应用到Excel。

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.虽然LT6556的性能优化，双电源供电，也可以作为低如4.5V的单电源操作。 Using dual 5V supplies, each amplifier draws only 9.5mA.使用双5V电源，每个放大器提请只有9.5毫安。 When disabled, the amplifiers draw less than 330µA and the outputs become high impedance.禁用时，放大器绘制小于330μA，输出成为高阻抗。 For applications requiring a fi xed gain of 2, refer to the LT6555 datasheet.对于需要Fi的2个固定的增益的应用，LT6555可用数据。

The LT6556 is available in 24-lead SSOP and ultra-compact 24-lead QFN packages.LT6556是在24引线SSOP和超小型24引脚QFN封è£
