TYPICAL PRODUCT TERM:

Pn = A

⋅ B ⋅ C ⋅ D ⋅ . . .

TYPICAL LOGIC FUNCTION:

AT OUTPUT POLARITY = H

Z = P0 + P1 + P2 . . .

AT OUTPUT POLARITY + L

Z = P0 + P1 + P2 + . . .

Z = P0

⋅ P1 ⋅ P2 ⋅ . . .

NOTES:

1. For each of the 10 outputs, either function Z

(Active-High) or Z (Active-Low) is available, but not

both. The desired output polarity is programmed

via the EX-OR gates.

2. ZX, A, B, C, etc. are user defined connections to

fixed inputs (I), and bidirectional pins (B).
