Quad 1 of 2 Line Data Selectors/Multiplexers
General Description
These data selectors/multiplexers contain inverters and
drivers to supply full on-chip data selection to the four out-

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 'T%txtmmentittd Operating Conditions " table will define
the conditions for actual device operation.
