Quad. 2-to-1-line Data Selectors/Multiplexers (with Noninverted Outputs)

Standard IC>General-Purpose Logics>HD74LS Series HD74HC157 Quad. 2-to-1-line Data Selectors/Multiplexers (with noninverted outputs) These devices each consist of four 2-input digital multiplexers with common select and strobe inputs. On the HD74HC157 when the strobe input is at logical L the four outputs assume the values as select from the inputs. When the strobe input is at a logical H the outputs assume logical L. HD74HC158 operates in the same manner, except that its outputs are inverted. Select decoding is done internally resulting in a single select input only. If enabled, the select input determines whether the A or B inputs get routed to their corresponding Y outputs. By Renesas Technology
