DESCRIPTION
TheM22101 and M22102 crosspoint switches con-
sist of 4 x 4 x 2 arrays of crosspoints (transmission
gates), 4-line to 16-linedecoders, and 16 latchcircuits.Anyone ofthe sixteen crosspoint pairscan be
selected by applying the appropriate four-line addressandanynumber ofcrosspoint pairscanbeON
simultaneously. Corresponding crosspointsin each
arrayare turned on and OFFsimultaneously, also.
In the M22101, the selected crosspoint pair can be
turnedon oroff by applyingalogical ONEor ZERO,
respectively, to the data input,and applying aONE
to the strobe input. When the device is”power-up”,
the state of the16 switches is indeterminate.
Therefore all switches mustbe turned offby putting
the strobe hight,data-in-low, and theaddressing all
switches in succession.
The selected pair of crosspoints in the M22102 is
turnedon by applying a logical ONE to the Ka(set)
input whilealogical ZEROis on theKb(reset) input,
and turned off by applying a logical ONE to the K
input while a logical ZEROis on theKainput.In this
respectthecontrol latches oftheM22102 aresimilar
to SET/RESET flip-flops. They differ, however, in
thatthe simultaneousapplication of ONEstothe K
and Kbinputs turns off (resets) all crosspoints. All
crosspoints in both devices must be turned off as
VDDis applied.
