Demystifying the LS157 Datasheet The Core Functionality
The LS157 datasheet primarily serves as a complete reference manual for the 74LS157, which is a quad 2-to-1 line data selector/multiplexer. In simpler terms, this chip allows you to select one of two input signals for each of its four independent channels and route that selected signal to the corresponding output. The selection is controlled by a single select input common to all four multiplexers. The datasheet details the logic behind this selection, presenting truth tables that clearly illustrate which input gets passed through to the output based on the state of the select pin. Understanding this fundamental operation is crucial for any application involving the LS157.
