DESCRIPTION
The M3493 contains a 12 x 8 array of crosspoint to-
gether with a 7 to 96 line decoder and latch circuits.
Anyoneof 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
oneor zero to the data in and the strobeinputat logi-

cal one. A reset signal can be used to turn off all the
switches together when is switched at logical one.
M3493 is available in 40 lead dual in-line plastic
package.
