APPLICATIONS
Matrices for decoding 16, 32, or 64 outputs are formed by using two, four, or
eight OD-335 PACs, respectively.
All but the one matrix containing the significant output
line must be inhibited.
In a 64-output matrix, seven of the eight octal matrices must be in-
hibited for unique activation of one of the 64 output lines.
The seven matrices are inhibited
by applying a ZERO to input X, Y, or Z.
For example, if binary bit 2
3
, 2
4
, and 2
5
are
ONEs, the seven matrices with outputs 0 through 55 are inhibited and only one output from
0
1
2
56 to 63 is activated, depending upon the state of bits 2 , 2 , and 2 .

trates the logic connections for multioctal matrices.
