Data Selectors/Multiplexers
General Description
These data selectors/multiplexers contain full on-chip
decoding to select the desired data source. The DM74150
selects one-of-sixteen data sources. The DM74150 has a
strobe input which must be at a LOW logic level to enable
these devices. A HIGH level at the strobe forces the W out-
put HIGH and the Y output (as applicable) LOW.
The DM74150 features an inverted (W) output only.

Absolute Maximum Ratings
(Note 1)
Note 1: 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 tables are not guaranteed at the absolute maximum ratings.
The "Recommended Operating Conditions" table will define the conditions
for actual device operation.
