Working Principles

The CY74FCT157ATDG4 is a digital multiplexer that selects one of four input data lines (B0-B3) based on the select inputs (A0-A2). The enable input (G) controls the output state. When G is low, the outputs (Y0-Y3) are in a high-impedance state, allowing other devices to drive the bus. When G is high, the selected input is routed to the corresponding output.

Detailed Application Field Plans

The CY74FCT157ATDG4 is commonly used in various digital systems where data selection and routing are required. Some specific application fields include:

  1. Data communication systems
  2. Microprocessor-based systems
  3. Industrial control systems
  4. Automotive electronics
  5. Consumer electronics
