NCS6416 : Low-Voltage, Bus-Controlled Video Matrix Switch he main function of the NCS6416 is to switch 8 video input sources to the 6 outputs. The NCS6416 operates with a low 5 V power supply. Each output can be switched to only one of the inputs, whereas any single input may be connected to several outputs.
