Working Principles

The 74LVQ157SJ operates based on the principles of digital logic. It uses the select (F) and enable (E) inputs to control the routing of data from the four input pins (A, B, C, D) to the output pin (Y). The select input determines whether the IC functions as a multiplexer or a demultiplexer. When the enable input is active, the selected input is routed to the output pin. Otherwise, the output remains in a high-impedance state.

Detailed Application Field Plans

The 74LVQ157SJ finds applications in various fields, including: 1. Data communication systems 2. Digital signal processing 3. Multiplexing audio/video signals 4. Industrial automation 5. Consumer electronics
