How do you connect two multiplexers together?

How do you connect two multiplexers together?

To achieve the first two MUX is connected in parallel and then the output of those two are feeded as input to the 3rd MUX as shown below. The control/select line of the first two MUX is connected together to form a single line (S0) and then the control line of the 3rd MUX is used as the second control/select signal.

What is ic4051?

The CD4051B is a single 8-Channel multiplexer having three binary control inputs, A, B, and C, and an inhibit input. The three binary signals select 1 of 8 channels to be turned on, and connect one of the 8 inputs to the output.

What does a 4051 chip do?

CD 4051 is an analog multiplexer and demultiplexer. It has very low OFF leakage current and low ON impedance. CD-4051 can be used in signal gating, analog to digital converter, digital to analog converter, analog and digital multiplexing and demultilplexing.

What is 2 channel multiplexer?

The 74LVC2G53 is a single-pole double-throw analog switch with a digital select input (S), two independent inputs/outputs (Y0 and Y1), a common input/output (Z) and a digital enable input (E). When E is HIGH, the switch is turned off.

What is a 4 to 1 multiplexer?

A 4-to-1 multiplexer consists four data input lines as D0 to D3, two select lines as S0 and S1 and a single output line Y. The select lines S0 and S1 select one of the four input lines to connect the output line.

What is application of multiplexer?

A Multiplexer is used to increase the efficiency of the communication system by allowing the transmission of data such as audio & video data from different channels via cables and single lines.

What is multiplexer IC?

A Multiplexer IC allows you to interface a number of pins, with a single pin, by using a set of state pins to determine which ones are connected. e.g. you could have 8 LEDs as Outputs, all controlled from a single output. You could also have 8 different switches as Inputs, which are all interfaced to a single input.

What is 74HC138?

The 74HC138 is a high speed CMOS device. The device accepts a three bit binary weighted address on input pins A0, A1 and A2 and when enabled will produce one active low output with the remaing seven being high. There are two active LOW enable inputs E1 and E2, and one active HIGH enable input E3.

What is a mux chip?

A multiplexer (mux) or a data selector or input selector is a combinational circuit device that selects one of N inputs and provides it on its output. A set of inputs called select lines determine which input should be passed to the output.

What is a multiplexer in digital electronics?

In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines.

What is multiplexer with diagram?

Multiplexer is a combinational circuit that has maximum of 2n data inputs, ‘n’ selection lines and single output line. One of these data inputs will be connected to the output based on the values of selection lines. Multiplexer is also called as Mux.

What is multiplexer with example?

Multiplexer means many into one. A multiplexer is a circuit used to select and route any one of the several input signals to a single output. A simple example of an non-electronic circuit of a multiplexer is a single pole multi-position switch. A mechanical switch cannot perform this task efficiently. …

How many channels does a cd4051b multiplexer have?

The CD4051B is a single 8-Channel multiplexer having three binary control inputs, A, B, and C, and an inhibit input. The three binary signals select 1 of 8 channels to be turned on, and connect one of the 8 inputs to the output. The CD4052B is a differential 4-Channel multiplexer having two binary control inputs, A and B, and an inhibit input.

What kind of circuit is a cd405xb demultiplexer?

The CD405xB analog multiplexers and demultiplexers are digitally-controlled analog switches having low ON impedance and very low OFF leakage current. These multiplexer circuits dissipate extremely low quiescent power over the full VDD – VSS and VDD – VEE supply voltage ranges, independent of the logic state of the control signals.

What is the INH of an analog switch cd4051?

The input signal of the prohibition terminal “INH” of analog switch CD4051 is used to control the gating of voltage follower CH3130, thereby perform demodulation to multiple analog signals. 2. CD4051 constructs 32-channel circuit

What are the logic characteristics of the cd4051b?

Logic-Level Conversion for Digital Addressing Signals of 3 V to 20 V (VDD– VSS= 3 V to 20 V) to Switch Analog Signals to 20 VP-P(VDD– VEE= 20 V) Matched Switch Characteristics, rON= 5 Ω (Typical) for VDD – VEE= 15 V Very Low Quiescent Power Dissipation Under All Digital-Control Input and Supply Conditions, 0.2 µW (Typical) at
