4-wide 2-input AND-OR-invert gate
DESCRIPTION The HEF4086B is a 4-wide 2-input AND-OR-invert (AOI) gate with two additional inputs (I8 or I9) which can be used as either expander or inhibit inputs by connecting them to any standard LOCMOS output. A HIGH on I8 or a LOW on I9 forces the output (O) LOW independent of the other eight inputs (I0 to I7). The output (O) is fully buffered for highest noise immunity and pattern insensitivity of output impedance.

4-wide 2-input AND-OR-invert gate
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.
