Dual 2-wide 2-input AND-OR-invert gate
DESCRIPTION
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.
