DM74150

Data Selectors/Multiplexers

General Description

These data selectors/multiplexers contain full on-chip

decoding to select the desired data source. The DM74150

selects one-of-sixteen data sources. The DM74150 has a

strobe input which must be at a LOW logic level to enable

these 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.
