CD4016 - Quad Bilateral Switch IC

CD4016 - Quad Bilateral Switch IC

The CD4x Series CD4016 is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is pin-for-pin compatible with CD4066B. 

The CD4016 is a CMOS IC with four analog switches, which can be controlled individually using a control pin. The signal can flow in either direction between the two pins of each switch.

Each switch has an enable pin (A) and two input/output pins (X and Y). When the enable pin is set to HIGH, current can flow between X and Y in either direction. However, when enable is LOW, no current can flow between the pins. Just like a switch.
