DM74S157N Quad 2-To-1 Selector For Bus Steering

DM74S157N is a clean way to switch a 4-bit path between two sources without building a mux from discrete gates. It’s used for mode selection, test routing, and data path steering where a shared connector or backplane needs controlled selection. DM74S157N provides four 2-to-1 data selectors with a common select and a separate strobe input, so you can enable outputs only when needed. It operates from 4.75 V to 5.25 V, aligning with standard 5 V logic supplies. The device selects true data (not inverted), which keeps downstream decode predictable. Place DM74S157N close to the source signals to limit trace stubs and reduce crosstalk. Request a quote for DM74S157N.
