What is multiplexer chip?
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.
How do you control a multiplexer?
Generally, the selection of each input line in a multiplexer is controlled by an additional set of inputs called control lines and according to the binary condition of these control inputs, either “HIGH” or “LOW” the appropriate data input is connected directly to the output.
How do I choose a multiplexer?
Some of the important considerations when selecting a multiplexer for expanding the MCU are the voltage range of the input signals, on-resistance, on-capacitance, on-leakage, and charge injection. These are explained in further detail in the Multiplexer Specifications section.
What is dual multiplexer?
Dual 4-input multiplexer. The 74HC153; 74HCT153 is a dual 4-input multiplexer. The device features independent enable inputs (nE) and common data select inputs (S0 and S1). For each multiplexer, the select inputs select one of the four binary inputs and routes it to the multiplexer output (nY).
Which one is IC for decoder?
74LS138 IC: Pin Diagram, Circuit and Applications. The decoder 74LS138 IC uses advanced technology like silicon (Si) gate TTL technology.
How is IC 74138 activated?
We take the popular 3 to 8 decoder Integrated Circuit 74138. The Integrated Circuit is of 16 pins. We have three input pins which are actively in high state and are classified as I2, I1 and I0. The outputs are actively in low state and are eight in number and are classified as O7*, O6*, …, O0*.
Which is the best analog switch and multiplexer?
We offer the industry’s broadest selection of low-on-resistance, high-performance analog switches and multiplexers. Maxim’s switch and mux ICs are designed for general-purpose use as well as specific applications, including applications requiring high-voltage operation (up to 200V).
What kind of chip is used for multiplexers?
The 74148 is a popular IC encoder chip for these kinds of applications. Microprocessor based systems with serial input and output ports can use multiplexers and demultiplexers to route serial data to and from a number of different destinations.
What kind of switches and multiplexers does Maxim make?
Switches and Multiplexers We offer the industry’s broadest selection of low-on-resistance, high-performance analog switches and multiplexers. Maxim’s switch and mux ICs are designed for general-purpose use as well as specific applications, including applications requiring high-voltage operation (up to 200V). All Analog Switch Mux < 5V
What kind of voltage does a multiplexer need?
Comprehensive portfolio of protection, precision and general-purpose switches and multiplexers to support end-to-end signal chain needs. This portfolio features a broad range of supply voltages (0.8 V to 36 V) to accommodate any mux and demux needs.
