Semiconductor CD22101, CD22102 x 4 x 2 Crosspoint Switch with Control Memory CD22101 and CD22102 crosspoint switches consist of 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 the sixteen crosspoint pairs can be selected by applying the appropriate four-line address, corresponding 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 turned on or off by applying a logic ONE or ZERO, respectively, to the data input, and applying a ONE to the strobe input.
When the device is “powered up”, the states of ...
