D ESC R I PT I O N The M 22101 and M22102 crosspoint switches consist of 4 x 4 x 2 arrays of c rosspoints (transmission gates), 4-line to 16-line decoders, and 16 latch circuits. Any one of the sixteen crosspoint pairs can be selected by applying the appropriate four-line address 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. P I N CO NNE C TI O N S
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.
