APPLICATION INFORMATION
Figure 4 shows two HEF4086B ICs connected to obtain an 8-wide 2-input AOI function.
The output (OA) of the first IC is fed directly into the I9B gate input of the second IC. Similarly,
any NAND gate output can be fed directly into the I9 gate input to obtain a 5-wide AOI function.
In addition, any AND gate output can be fed directly into the I8 gate input with the same result.

Logic equation for Fig.4:
OB = I0A ⋅ I1A + I2A ⋅ I3A + I4A ⋅ I5A + I6A ⋅ I7A + I0B ⋅ I1B + I2B ⋅ I3B + I4B ⋅ I5B + I6B ⋅ I7B
