MAX4359/MAX4360/MAX4456 is a low-cost video crosspoint switch that can connect four (MAX4359) or eight (MAX4360/MAX4456) video inputs to any buffered output, with three-state output capability and internal programmable active loads, it is feasible to parallel multiple devices to form larger switch arrays.
The MAX4359, MAX4360 and MAX4456 are low‑cost video cross‑point switches that reduce component count and board space. They provide 4×4, 8×4 and 8×8 matrix configurations respectively, with internal high‑speed buffers capable of driving 400 Ω and 20 pF loads.
