NSC 9312

9312/DM9312 One of Eight Line
Data Selectors/Multiplexers
General Description
Features
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.

Absolute Maximum Ratings (Note)
Note: The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaranteed. 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.
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales
Office/Distributors for availability and specifications.
