DESCRIPTION
The M3493 contains a 12 x 8 array of crosspoint to-
gether with a 7 to 96 line decoder and latch circuits.
Anyone of the 96 switches can be addressed by se-
lecting the appropriate 7 input bits. The selected
switch can be turned on or off by applying a logical
one or zero to the data in and the strobe input at logi-
