Working Principles

The 74VHC4066MTC operates based on the principle of field-effect transistors (FETs). Each channel consists of two FETs that act as switches. The control inputs determine the state of these switches, allowing the desired signals to pass through or be blocked.

When the control inputs are appropriately configured, the FETs conduct and establish a low-resistance path between the input and output terminals. Conversely, when the control inputs are in a different state, the FETs turn off, effectively isolating the input and output.
