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 appropri a te 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.

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.

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 K

input while a logical ZERO is on the K

and turned off by applying a logical ONE to the K

input while a logical ZERO is on the K

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 K

and K

crosspoints in both devices must be turned off as
