54150/DM54150/DM74150, 54151A/DM54151A/DM74151A Data Selectors/Multiplexers
June 1989
54150/DM54150/DM74150,
54151A/DM54151A/DM74151A
Data Selectors/Multiplexers
General Description
These data selectors/multiplexers contain full on-chip decoding 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, whereas the 150 has an inverted (W) output only.
The 151A incorporates address buffers which have symmetrical propagation delay times through the complementary 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 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.
