What is CD74HC4067?
The CD74HC4067 is a 16-Channel Analog Multiplexer/Demultiplexer. A multiplexer of this sort really just acts as a 16 to one 1 switch. The 4 digital pins are used to set HIGH or LOW, in a binary fashion (0-15) to determine what pin “SIG” is connected to.
How does a 16 channel multiplexer work?
It works with both digital and analog signals (the voltage can’t be higher than vcc) and the connections function in either direction. To control it, connect 4 digital outputs to the chip’s address select pins (s0-s3), and send it the binary address of the channel you want (see the datasheet for details).
Which IC is used for multiplexer?
List of ICs which provide multiplexing
| IC No. | Function | Output State |
|---|---|---|
| 74×352 | Dual 4:1 mux. | Output is inverted input |
| 74x151A | 8:1 mux. | Both outputs available (i.e., complementary outputs) |
| 74×151 | 8:1 mux. | Output is inverted input |
| 74×150 | 16:1 mux. | Output is inverted input |
What is select lines in multiplexer?
select lines, which are used to select which input line to send to the output. Conversely, a demultiplexer (or demux) is a device taking a single input and selecting signals of the output of the compatible mux, which is connected to the single input, and a shared selection line.
What is 8×1 multiplexer?
An 8-to-1 multiplexer consists of eight data inputs D0 through D7, three input select lines S0 through S2 and a single output line Y. Depending on the select lines combinations, multiplexer selects the inputs.
What are the two basic multiplexing techniques?
There are mainly two types of multiplexers, namely analog and digital. They are further divided into Frequency Division Multiplexing (FDM), Wavelength Division Multiplexing (WDM), and Time Division Multiplexing (TDM).
What are applications of multiplexer?
Applications of Multiplexer Multiplexer allow the process of transmitting different type of data such as audio, video at the same time using a single transmission line. Telephone Network – In telephone network, multiple audio signals are integrated on a single line for transmission with the help of multiplexers.
What is a cd74hc4067 16 channel multiplexer?
CD74HC4067 16-Channel Multiplexer Features The CD74HC4067 16-Channel analog-digital multiplexer module can be used when there are many analog inputs in a circuit. In this case, one of these inputs needs to be selected and processed each time. This multiplexer can be used to select from 16 analog inputs.
How does the cd4067 work?
The CD4067 is a 16-channel multiplexer with four binary control inputs, A, B, C, D, and an inhibit input, arranged so that any combination of the inputs selects one switch. A logic “1” present at the inhibit input turns all channels off.
How many analog inputs does this multiplexer have?
This multiplexer can be used to select from 16 analog inputs. There are four S0-3 pins, which by giving appropriate values, one of the analog inputs is set as the output in the SIG pin. You can see the pinout of this module in the image below.
What is an IC 74hc4067?
That’s a mouthful – however in simple form it’s an IC that can direct a flow of current in either direction from one pin to any one of sixteen pins. Another way to think abou it is that you can consider the 74HC4067 to be a digital replacement to those rotary switches that allow you to select one of sixteen positions.
