19-1389; Rev 1; 12/99 Low-Cost 4x4, 8x4, 8x8 Video Crosspoint Switches General Description The MAX4359/MAX4360/MAX4456 low-cost video crosspoint 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.
