DESCRIPTION
The M22101 and M22102 crosspoint switches con-
sist of 4 x 4 x 2 arrays of crosspoints (transmission
gates), 4-line to 16-line decoders, and 16 latch cir-
cuits. Any one of the sixteen crosspoint pairs can be
selected by applying the appropriate four-line ad-
dress and any number of crosspoint pairs can be ON
simultaneously. Corresponding crosspoints in each
array are turned on and OFF simultaneously, also.
Therefore all switches must be turned off by putting
the strobe hight, data-in-low, and the addressing all
switches in succession.
The selected pair of crosspoints in the M22102 is
turned on by applying a logical ONE to the Ka (set)
input while a logical ZERO is on the Kb (reset) input,
and turned off by applying a logical ONE to the Kb
input while a logical ZERO is on the Ka input. In this
respect the control latches of the M22102 are similar
to SET/RESET flip-flops. They differ, however, in
that the simultaneous application of ONEs to the Ka
and Kb inputs turns off (resets) all crosspoints. All
crosspoints in both devices must be turned off as
VDD is applied.
In the M22101, the selected crosspoint pair can be
turned on or off by applying a logical ONE or ZERO,
respectively, to the data input, and applying a ONE
to the strobe input. When the device is ”power-up”,
the state of the 16 switches is indeterminate.
