DESCRIPTION
The HEF4085B is a dual 2-wide 2-input AND-OR-invert
gate, each with an additional input (A
4
or B
4
) which can be
used as either an expander input or an inhibit input. A
HIGH on A
4
or B
4
forces the output (O
A
or O
B
) LOW
independent of the other inputs (A
0
to A
3
or B
0
to B
3
). The
outputs O
A
and O
B
are fully buffered for highest noise
immunity and pattern insensitivity of output impedance.
