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.
