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).
