87-3-209 CROSSPOINT SWITCHING ARRAY Abstract: A crosspoint switching array of a matrix of cross- point switches connected in rows and columns. Each crosspoint switch includes an MOS inverter circuit for propagating a digital signal from crosspoint-to- crosspoint along its row. Each crosspoint switch includes a first MOS switch connected to the preceding crosspoint switch in the column and a second MOS switch connected to its row. The second switch is activated to connect the row to the column at a particular crosspoint. Otherwise, the first switch is activated to connect the crosspoint switch to the preceding crosspoint switch in the column. The output of the first or second switch is applied to an MOS inverter circuit for driving the following crosspoint switch in the column.
