Product Descriptions

The HEF4085B is a dual 2-wide 2-input AND-OR-invert gate, each with an additional input (A4 or B4) which can be used as either an expander input or an inhibit input. A HIGH on A4 or B4 forces the output (OA or OB) LOW independent of the other inputs (A0 to A3 or B0 to B3). The outputs OA and OB are fully buffered for highest noise immunity and pattern insensitivity of output impedance.
