Working Principles
The DG442BDJ is a digital multiplexer that operates based on the control inputs (A0-A3). These inputs determine which of the four data inputs (B0-B3) is selected and routed to the output pin (Y). The enable pin (E) controls the overall functionality of the multiplexer.
When the enable pin is high, the selected data input is passed through to the output pin. When the enable pin is low, the output is in a high-impedance state, effectively disconnecting it from the inputs.
