Working Principles
The N74F257AN,602 is a 4-to-1 multiplexer/demultiplexer IC. It operates by selecting one of the four input data lines (A0-A3 or B0-B3) based on the control signal provided at the enable input (E). When E is high, the multiplexer function is active, and the selected input line is routed to the output lines (Y0-Y3). Conversely, when E is low, the demultiplexer function is active, and the input lines (A0-A3 or B0-B3) are connected to the corresponding output line (Y0-Y3).
Detailed Application Field Plans
The N74F257AN,602 finds applications in various digital systems where data routing and selection are required. Some potential application fields include: 1. Data communication systems 2.
