DM74ALS251SJ

The DM74ALS251SJ is an IC (Integrated Circuit) component that belongs to the 74ALS series of high-performance, advanced low-power Schottky TTL (Transistor-Transistor Logic) family. It is a multiplexer device with eight inputs and one output, designed to efficiently select and route one of the eight data inputs to the output based on the value of control inputs. Key features of the DM74ALS251SJ include: 1. Data Inputs: The IC has eight data inputs (A0-A7), through which the input data is provided. These inputs are digitally controlled and can be either high logic level (typically 2.7V to 5.5V) or low logic level (typically 0V to 0.8V). 2. Select Inputs: This component has three select inputs (S0, S1, and S2), which determine the path to be selected. Based on the combination of these inputs, one of the eight data inputs is chosen and transferred to the output. 3. Output Enable: The IC incorporates an output enable input (OE) that enables or disables the selection on the output. When OE is high, the selected data input is transferred to the output. Conversely, when OE is low, the output is in a high-impedance state. 4. Low Power Consumption: The DM74ALS251SJ is designed to operate at high speeds while consuming low power
