MAX4456EPL

低成本的4x4 ， 8x4的8×8视频交叉点开关 Low-Cost 4x4, 8x4, 8x8 Video Crosspoint Switches

General Description

The MAX4359/MAX4360/MAX4456 low-cost video cross point switches are designed to reduce component count, board space, design time, and system cost. Each contains a matrix of T-switches that connect any of their four MAX4359 or eight MAX4360/MAX4456 video inputs to any of their buffered outputs, in any combination. Each matrix output is buffered by an internal, high-speed 250V/µs, unity-gain amplifier that is capable of driving 400Ω and 20pF at 2.6Vp-p. For applications requiring increased drive capability, buffer the MAX4359/MAX4360/MAX4456 outputs with the MAX497 quad, gain-of-two video line driver.
