Working Principles

The SN74LVC157APWG4 is a quad 2-line to 1-line data selector/multiplexer. It selects one of the four data inputs based on the select inputs and routes it to the output. The active-low enable input (G) controls the operation of the device. When G is low, the selected data input is passed to the output. When G is high, all outputs are in a high-impedance state.

Detailed Application Field Plans

The SN74LVC157APWG4 can be used in various applications, including but not limited to:

1. Data routing and selection in microcontrollers and digital signal processors.
2. Address decoding in memory systems.
3. Input/output expansion in embedded systems.
4. Multiplexing control signals in communication systems.
5. Logic level conversion in mixed-voltage systems.
