DM74150Data Selectors/MultiplexersGeneral DescriptionThese data selectors/multiplexers contain full on-chipdecoding to select the desired data source. The DM74150selects one-of-sixteen data sources. The DM74150 has astrobe input which must be at a LOW logic level to enablethese 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.

Features 150 selects one-of-sixteen data lines Performs parallel-to-serial conversion Permits multiplexing from N lines to one line Also for use as Boolean function generator Typical average propagation delay time, data input to W

output: 11 ns Typical power dissipation: 200 mW

74150Absolute Maximum Ratings(Note 1)

Note 1: The Absolute Maximum Ratings are those values beyond whichthe safety of the device cannot be guaranteed. The device should not beoperated at these limits. The parametric values defined in the ElectricalCharacteristics tables are not guaranteed at the absolute maximum ratings.The Recommended Operating Conditions table will define the conditionsfor actual device operation.

Recommended Operating Conditions

Note 2: All typicals are at VCC = 5V, TA = 25C.Note 3: Not more than one output should be shorted at a time.Note 4: ICC is measured with the strobe and data select inputs at 4.5V, all other inputs and outputs OPEN.
