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 gat e 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.
When 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 successi o n.
