Data Selectors Multiplexers
General Description
These data selectors multiplexers contain inverter drivers
to supply full complementary on-chip binary decoded data
selection
The 9312 is a single 8-bit multiplexer with complementary
outputs and a strobe control When the strobe is low the
function is enabled When a high logic level is applied to the
strobe the output is forced to the logic zero state regardless
of the logic level of the data inputs

Note
The ``Absolute Maximum Ratings'' are those values
beyond which the safety of the device cannot be guaran-
teed The device should not be operated at these limits The
parametric values defined in the ``Electrical Characteristics''
table are not guaranteed at the absolute maximum ratings
The ``Recommended Operating Conditions'' table will define
the conditions for actual device operation
