Data Selectors Multiplexers
General Description
These data selectors multiplexers contain full on-chip de-
coding to select the desired data source The 150 selects
one-of-sixteen data sources the 151A selects one-of-eight
data sources The 150 and 151A have a strobe input which
must be at a low logic level to enable these devices A high
level at the strobe forces the W output high and the Y output
(as applicable) low
The 151A features complementary W and Y outputs where-
as the 150 has an inverted (W) output only
The 151A incorporates address buffers which have sym-
metrical propagation delay times through the complementa-
ry paths This reduces the possibility of transients occurring
at the output(s) due to changes made at the select inputs
even when the 151A outputs are enabled (i e strobe low)

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
