ABSTRACT:
An improved matrix switch circuit comprising an array of analog switches disposed in the form of a matrix and one or more control memories for storing control signals which cause their respective switches of the array to open or close. An interface is provided between the control memories and the array of the switches. The interface receives the control signals from the control memories and holds them. The held signals are then supplied to the switches of the array. While the switches of the array are being controlled according to the control signals held in the interface, the contents of the control memories can be changed at any desired instant.
