For an 8-to-1 multiplexer (8:1 MUX), the common IC used is the 74LS157 or 74HC157, depending on whether you're using standard logic (LS) or high-speed CMOS (HC) logic.
The 74LS157 is a 4-bit multiplexer, but you can use two of these ICs to create an 8-to-1 multiplexer by connecting them together in a way that allows you to select from 8 inputs.
If you're looking for a single-chip solution for an 8-to-1 MUX, you might also find specific multiplexers like the 74LS251 or 74HC251 that are designed specifically for an 8-input multiplexer. These ICs have 8 input lines, 3 control lines (for selection), and a single output.
So, depending on your application and logic family (LS, HC, etc.), you can pick one of these ICs.
