Data SelectorsMultiplexers

General Description

These data selectorsmultiplexers 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 (ie strobe low)
