HEF4086B - 4-wide 2-input AND-OR-invert gate
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
