CD4066 is a part of the CD4000 IC series. The CD4066 is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is pin-for-pin compatible with CD4016BC. The IC has a wide range of working voltages and conditions and has direct compatibility with CMOS, TTL, and NMOS devices. The IC offers features such as squelch controlling and ESD barring.
What is Bilateral Switch?
A Bilateral switch is an analog switch that can operate forward or reverse bias. This means that either side of the switch can be used as the input. So current can flow in one direction and the other direction, depending on which side is the input. A bilateral switch acts as a single pole, single throw switch. Each switch also has a control terminal. In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH
