The 74F157ALC is a popular Integrated Circuit (IC) component that belongs to the 74F series of high-speed TTL logic family. It is a quad 2-input multiplexer with output enable, which means it can select one of four data sources based on two select inputs. Here is an overview of its key features:
1. High-Speed Operation: The 74F157ALC is known for its fast operation, with a propagation delay of just 6 nanoseconds (typical) and a maximum frequency rating of 140 MHz. This makes it suitable for applications where speed is crucial.
2. Quad 2-Input Multiplexer: It consists of four individual 2-input multiplexers, allowing the selection of one of the four data sources. Each multiplexer has two data inputs (A and B), a common select input (S), and an output (Y).
3. Output Enable Functionality: In addition to the select inputs, the 74F157ALC includes an output enable (OE) pin. When OE is low, the outputs are enabled, and the selected data is available at the output pins. When OE is high, the outputs are in a high-impedance state.
4. Input and Output Voltage Levels: The IC operates using a supply voltage (VCC) ranging from 4.5V to 5.5V
