Analog switches, multiplexers, and demultiplexers are all components of integrated circuits used in analog and mixed-signal circuits. They are used to route and control analog signals in an efficient manner. The SN74HC4851PWR is an example of such a component, used in a variety of applications.

Application Fields

The SN74HC4851PWR is a precision multiplexer designed for use in high-precision analog applications, such as analog-to-digital converters, audio/video multiplexing, digital signal processing, and high-speed switching. It is capable of handling up to four channels, each with switchable on/off functionality. The SN74HC4851PWR is also capable of switching 90mA of current and is available in a surface-mount package. This makes it well-suited to many high-speed digital and analog applications.

The SN74HC4851PWR is often used in combination with other components such as digital-to-analog converters (DACs) and analog-to-digital converters (ADCs). This combination makes it possible to create sophisticated analog circuit designs that can boost the performance of embedded systems. For example, the SN74HC4851PWR can be used along with a DAC and ADC to improve the dynamic range of a system or to create filtering or automatic gain control systems.

The SN74HC4851PWR is also well-suited to many audio applications, mainly due to its fast switching times and low power consumption. It can be used in active crossover networks, speaker systems, and audio amplifiers for both two-channel stereo and four-channel multi-channel audio systems. It can also be used in audio processors and audio mixers to create a variety of custom audio effects.

Working Principle

The SN74HC4851PWR is a digitally controlled multiplexer. It has two input signals, A and B, and four output channels, designated A0-A3. When the control signal, labeled SEL, is low, output A0 will be equal to the first input, A, and A1-A3 will be equal to the second input, B. When the control signal is high, the second output, B, will be connected to the first input and the first output will be connected to the second input.

The SN74HC4851PWR has two control terminals, labeled "0/1" and "2/3." When these terminals are set to "0/1" or "2/3," the corresponding output channel will be routed to the corresponding input channel. For example, if "0/1" is set to 0, then output A0 will be equal to input A. When the control signal, SEL, is high, the second output, B, will be connected to output A0 and the first output, A, will be connected to output B.

The SN74HC4851PWR is also equipped with an enable pin, labeled "EN," which allows the multiplexer to be enabled or disabled. When the EN pin is high, the SN74HC4851PWR is enabled. When the EN pin is low, the multiplexer is disabled and no signals will be routed between the inputs and outputs.

Conclusion

The SN74HC4851PWR is a precision analog multiplexer designed for use in high-precision circuits. It is capable of switching 90 mA of current and is available in a surface-mount package. The SN74HC4851PWR can be used in a variety of applications, such as analog-to-digital converters, digital signal processing, audio/video multiplexing, active crossover networks, and audio amplifiers.

The SN74HC4851PWR is digitally controlled, with two input signals, four output channels, two control terminals, and an enable pin. When the control signal is low, output A0 will be equal to input A, and A1-A3 will be equal to input B. When the control signal is high, output B is connected to output A0 and output A is connected to output B. The enable pin allows the multiplexer to be enabled and disabled.
