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 (A4or B4) which can be
used as either an expander input or an inhibit input. A
HIGH on A4or B4forces the output (OAor OB) LOW
independent of the other inputs (A0to A3or B0to B3). The
outputs OAand OBare fully buffered for highest noise
immunity and pattern insensitivity of output impedance.
