The 74LS258APC is a specific integrated circuit (IC) component that belongs to the 74LS series of logic chips. It is a quad 2-input multiplexer with three-state outputs. Here are the key features and functions of the 74LS258APC:
1. Multiplexer Function: The primary function of this IC is as a multiplexer. It has four individual 2-input multiplexers that enable the selection of one data input out of two possible inputs for each multiplexer.
2. Three-State Outputs: The 74LS258APC has three-state outputs, which means that the outputs can be in one of three states: high (logic 1), low (logic 0), or high-impedance (disconnected). This feature allows multiple ICs to be connected together and share a common bus line, without interfering with each other.
3. Enable Inputs: Each of the four multiplexers has an independent enable input, which allows the user to control the switching of each multiplexer individually. When the enable input is low (logic 0), the multiplexer output goes into a high-impedance state, disconnecting it from the output line.
4. Cascadable: The 74LS258APC is designed to be cascaded, meaning that multiple ICs can be connected together to increase the number of input channels
