The IC component 54F258AFMQB, also known as Quad 2-Input Multiplexer, is a widely used electronic component in digital circuits. It is a multiplexer that allows the selection of one of four data inputs and passes the selected input to the output. Here are its key features:
1. Input and output configuration: The 54F258AFMQB has four data inputs designated as A, B, C, and D. It also has two select inputs, labeled S1 and S0, which control the input selection. The output delivers the selected data input to the output pin, designated as Y.
2. Multiplexing functionality: The central purpose of this IC is to perform multiplexing. Based on the input combinations of S1 and S0, it selects one of the data inputs and forwards it to the output. The truth table of the IC helps determine the specific input-output behavior.
3. Fast operation: The "54F" in the part number indicates that it is a fast TTL logic device. This means it operates at higher speeds and offers improved performance compared to standard TTL logic devices. It can handle high-frequency signals efficiently.
4. High current handling: The IC is designed to handle relatively high currents (Fanout of 15 LS-TTL loads). This capability ensures that it can drive multiple components or function as an input to other digital circuits without causing degradation in performance
