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 strobe inputat logi-

DIP40

ORDERING NUMBER : M3493B2 (*)

(*) It substitutes the obsolete M3493B1.

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.
