151 AVG Semiconductors DDi Technical Data DV74HCT151 Available O2, 1995 8-Input Data DV74HC151 Selector/Multiplexer DV74HCT151 This device selects one of the 8 binary Data Inputs, as deter- mined by the Address Inputs. The Strobe pin must be at alow level for the selected data to appear at the outputs. If Strobe is high, the Y output is forced to a low level and the Y output N Suffix is forced to a high level.
