DESCRIPTION The M22100 combines a 4 x 4 array of crosspoints (transmission gates) with a 4 line to 16 line decoder and 16 latch circuits. Any one of the sixteen transmission gates (crosspoints) can be selected by applying the appropriate four line address. The selected transmission gate can be turned on or off by applying a logical one or zero, respectively, to the data input and strobing the
strobe input to a logical one. Any number of the transmission gates can be ON simultaneously. W hen the required operating power is applied to the 22100, the states of the 16 switches are indeterminate. Therefore, all switches must be turned off by putting the strobe high and data in low, and the addressing all switches in succession.
