M22102 Overview
The M22101 and M22102 crosspoint switches consist of 4 x 4 x 2 arrays of crosspoints (transmission gates), 4-line to 16-line decoders, and 16 latch circuits. Any one of the sixteen crosspoint pairs can be selected by applying the appropriate four-line address and any number of crosspoint pairs can be ON simultaneously. Corresponding crosspoints in each array are turned on and OFF simultaneously, also.
