CMOS 4 x 4 x 2 Crosspoint Switch
Description
= 12V
CD22101 and CD22102 crosspoint switches consist of
DD
4 x 4 x 2 arrays of crosspoints (transmission gates) with a
4-line to 16-line decoder and 16 latch circuits. Any one of
/2
the sixteen crosspoint pairs can be selected by applying
DD
the
appropriate
crosspoints in each array are turned on and off
simultaneously. Any number of crosspoints can be turned
on simultaneously.
In the CD22101, the selected crosspoint pair can be
= 1k
turned on or off by applying a logic ONE or ZERO,
L
respectively, to the data input, and applying a ONE to the
strobe input. When the device is “powered up”, the states
of the 16 switches are indeterminate. Therefore, all
switches must be turned off by putting the strobe high,
data-in low, and then addressing all switches in
succession.
The selected pair of crosspoints in the CD22102 is turned
on by applying a logic ONE to the K
logic ZERO is on the K
a logic ONE to the K
