• 描述

  The LT ^® 6554 is a high-speed triple video buffer with an internally fixed gain of 1. ^LT®6554是一种高速的内部固定增益为1的三路视频缓冲器。 The individual buffers are optimized for performance with a 1k load and feature a 2V _PP full signal bandwidth of 400MHz, making them ideal for driving very high-resolution video signals.个别缓冲区性能优化与1K负载和功能提供2V _PP 400MHz的信号带宽，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 amplifier boost channel separation to 90dB, allowing the LT6554 to excel in many highspeed applications.为每个放大器提升到90dB通道分离的独立的电源供电引脚，使LT6554在许多高速应用到Excel。

  While the performance of the LT6554 is optimized for dual supply operation, it can also be used on a single supply as low as 4.5V.虽然LT6554的性能优化双电源供电，它也可以被用来作为低如4.5V的单电源。 Using dual 5V supplies, each amplifier draws only 8mA.使用双5V电源，每个放大器的投篮仅为8mA。 When disabled, the amplifiers draw less than 100uA and the outputs become high impedance.禁用时，放大器绘制小于100uA的输出成为高阻抗。 Furthermore, the amplifiers are capable of turning on in less than 50ns, making them suitable for multiplexing and portable applications.此外，该放大器能转动小于50ns，使它们适合用于复用和便携式应用。

  The LT6554 is manufactured on Linear Technology's proprietary low voltage complementary bipolar process and is available in the 16-lead SSOP package that fits in the same PCB area as an SO-8 package. LT6554是凌力尔特公司专有的低电压互补双极工艺制造，可在16引脚SSOP封装，适合在SO-8封装相同的PCB面积。
