The MC14506UB is an expandable AND–OR–INVERT gate with inhibit
and 3–state output. The expand option allows cascading with any other gate,
which may be carried as far as desired as long as the propagation delay
added with each gate is considered. For example, the second AOI gate in
this device may be used to expand the first gate, giving an expanded 4–wide,
2–input AOI gate. This device is useful in data control and digital multiplexing
applications.

This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, pre-
cautions must be taken to avoid applications of
any voltage higher than maximum rated volt-
ages to this high–impedance circuit. For proper
operation, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.
