Data Selectors Multiplexers
General Description Features
These data selectors multiplexers contain full on-chip de- Y 150 selects one-of-sixteen data lines
coding to select the desired data source The 150 selects Y 151A selects one-of-eight data lines
one-of-sixteen data sources the 151A selects one-of-eight Y Performs parallel-to-serial conversion
data sources The 150 and 151A have a strobe input which Y Permits multiplexing from N lines to one line
must be at a low logic level to enable these devices A high Y Also for use as Boolean function generator

The 151A features complementary W and Y outputs where- 150 11 ns
as the 150 has an inverted (W) output only 151A 9 ns
The 151A incorporates address buffers which have sym- Y Typical power dissipation
