What is 4066 IC?
The 4066 is pin-compatible with the 4016, but has a significantly lower on impedance and more constant on resistance over the full range of input voltage. Therefore, the 4066 is preferable to the 4016 in most cases….Practical Electronics/IC/4066.

How does 4066 work?
The 4066 really functions as an analog switch. The 4066 is an IC composed of switches which are designed to switch analog signals via digital control. The 4066 is a quad bilateral switch circuit, meaning that is composed of 4 switches. Each switch has a single input and a single output terminal.
What is a quad bilateral switch?
The CD4016 is a Quad Bilateral Switch IC, that is it has four switches which can be controlled individual using a control pin. These switches can conduct in both the directions making it bilateral, it is commonly used for multiplexing analog or digital signals.
What does a bilateral switch do?
The analogue (or PETR) switch, also called the bilateral switch, is an electronic component that behaves in a similar way to a relay, but has no moving parts. The switching element is normally a pair of MOSFET transistors, one an N-channel device, the other a P-channel device.
What is a 4016?
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).
Are switches analog or digital?
The switch control input for both kinds of switches is usually a digital signal input (called an input select), although other control triggers can be used to make specific applications easier to implement.
Is a switch an analog or digital input?
An analog switch will transmit or block a signal with a range of voltages from 0V to the maximum rating of the switch. This transfer from input to output is essentially linear. A digital switch transmits a signal that has only two levels, high and low.
What is the difference between 4016 and 4066?
The 4066 is pin-compatible with the 4016, but has a significantly lower on impedance and more constant on resistance over the full range of input voltage. Therefore, the 4066 is preferable to the 4016 in most cases.
What type of signal does a switch produce?
A switch is an example of a digital signal producing device. The output is either on or off and produces either a high or low voltage. Electronic Control Units monitor inputs, process input signals, and generate output signals. Inputs − Switches and sensors send input signals to ECUs.
Is fan a digital device?
Today, myriad devices are digital including a smartphone, tablet and smartwatch. In contrast, there are numerous non-digital (analog) devices, such as a thermometer, electric fan and bicycle. Automobiles, washing machines and many other products are both digital and analog.
Is relay digital or analog?
An analog switch acts like a solid-state relay (i.e., with no moving parts). Analog switches are able to pass or isolate both analog and digital signals, but digital switches can only pass or isolate digital signal lines.
Where can I get a 4066 quad bilateral switch circuit?
One place it can be obtained is at Taydaelectronics at the following link: TaydaElectronics- 4066 Quad Bilateral Switch IC . The 4066 is a 14-pin chip.
What is the control logic of a 4066 switch?
So, the control logic is when a LOW signal is feeding the control terminal, the switch is open or OFF. When a HIGH signal is feeding the control terminal, the switch is closed or ON. In this circuit, we will show the basic functionality of the 4066 chip by passing analog signals through 2 of the switches by digital control.
What are the pins on the 4066 chip?
The pinout of the 4066 chip is shown below. As the quad term implies, the 4066 is composed up of 4 switches. The switches are labeled from 1 to 4. Each switch has an input, output, and control terminal. The control terminal enables the input to go to output. V DD and ground, pins 14 and 7, are the power pins.
