Description
CD22100 combines a 4 x 4 array of crosspoints (transmis-
sion gates) with a 4-line to 16-line decoder and 16 latch
circuits. Any one of the sixteen transmission gates (cross-
points) can be selected by applying the appropriate four line
address. The selected transmission gate can be turned on or
off by applying a logic one or zero, respectively, to the data
input and strobing the strobe input to a logic one. Any
number of the transmission gates can be ON simultaneously.
When the required operating power is applied to the
CD22100, 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 then addressing all switches
in succession.
