What is multiplexer 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. For a 2:1 (two-to-one) MUX, when sel is 0, q = a and when sel is 1, q = b.

What is IC 74157?

Description:- 74HC157 is a 16 Pin Quad 2-Input Multiplexer IC having 2V to 6V Operating Voltage range with 1uA Low Input current and high noise immunity. It select 4 bits of data from two sources under the control of a common data select input (S). The enable input (E) is active LOW.

What is a 16 channel analog multiplexer?

MC14067B: 16-Channel Analog Multiplexer/Demultiplexer (Mux/Demux) The MC14067 multiplexer/demultiplexer is a digitally controlled analog switch featuring low ON resistance and very low leakage current. This device can be used in either digital or analog applications.

What is an 8 bit 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. Since the number data bits given to the MUX are eight, then 3 bits (23 = 8) are needed to select one of the eight data bits.

How does multiplexer work?

A multiplexer is a system of multiple inputs and just one output to receive signals coming from multiple acquisition networks. The device transfers all input signals to a microprocessor, which receives and processes the data, transmits it to the output devices, and controls the system as a whole.

How does multiplexer IC work?

Basics of Multiplexers: Here the switch has multiple inputs D0, D1, D2 and D3 but it has only one Output (Out) pin. The Control knob is used to select one of the four available data and this data will be reflected on the output side. This way the user can select the required the signal among many available signals.

What are the different available multiplexer IC?

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….List of ICs which provide multiplexing.

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).

What are logic gates?

Logic gates are the basic building blocks of any digital system. It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a certain logic. Based on this, logic gates are named as AND gate, OR gate, NOT gate etc.

What kind of chips are in the 74HC series?

74HC Series of Low Power, High Speed, CMOS Logic Gate Chips including AND, OR, NAND Gates as well as counters, shift registers and multiplexers. 74HC221 Dual Mono.

What is the general description of the 74hc151?

General description. The 74HC151; 74HCT151 are 8-bit multiplexer with eight binary inputs (I0 to I7), three select inputs (S0 to S2) and an enable input (E ). One of the eight binary inputs is selected by the select inputs and routed to the complementary outputs (Y and Y ).

How many binary inputs does a 74hct151 have?
