Working Principles

The SN74LVC2G157YEPR operates by selectively routing or demultiplexing digital signals based on the control inputs. The A and B inputs determine which data input is connected to the output, controlled by the logic levels applied to these pins. The output can be enabled or disabled using the G (Gating) input. When the G input is low, the outputs are in a high-impedance state.
