Working Principles

The 74LVC2G66DC-Q100H is a dual bilateral switch that facilitates the transfer of digital signals between two separate circuits. It operates based on control inputs, which determine the connection between the A-side and B-side terminals. When the control input is high, the switch is closed, allowing signal transmission. Conversely, when the control input is low, the switch is open, isolating the two circuits.
