The MC74HC157AN is an IC (integrated circuit) component known as a quad 2-input multiplexer. This versatile and widely used device is part of the 74HC series, which signifies its compatibility with the industry-standard 74HC logic families. The MC74HC157AN offers various key features that make it convenient for electronic circuits and systems.
One of the essential features of the MC74HC157AN is its ability to function as a multiplexer. A multiplexer is a digital circuit that takes multiple input signals and selects one of them based on the select inputs. In the case of the MC74HC157AN, it has four data inputs (D0, D1, D2, and D3), two select inputs (S0 and S1), and one output (Y). Based on the select inputs, the output of the IC will correspond to one of the data inputs.
Each of the four data inputs can either be high (logic 1) or low (logic 0), and the appropriate input is selected by the select inputs. This enables the circuit designer to effectively route multiple signals through a single channel or input, saving valuable space and reducing complexity.
Another key feature of the MC74HC157AN is its compatibility with TTL (Transistor-Transistor Logic) voltage levels. The IC operates within a range of 2.0 to 6
