The SN74LV4051ATPWRQ1 is a part of the Analog Switches, Multiplexers, Demultiplexers interface family from Texas Instruments. It is a four-channel analog multiplexer/demultiplexer that gives designers the ability to easily switch between a group of 4 possible analog signals. The chip is capable of handling both analog and digital signals, allowing designers to use the same chip to deal with both different types of signals.

Application Field

The SN74LV4051ATPWRQ1 is ideal for applications that require the switching between various input signals such as audio and video, or switching between channels on a radio frequency tuner. It is also useful in applications that need to switch between various output signals, such as video selectors, or in applications that require multiplexed or demultiplexed signals. It is especially useful in low-voltage applications, where it can be powered from a single 1.65 to 3.6Volts of power supply.

Working Principle

The SN74LV4051ATPWRQ1 is composed of four independent switches which can be independently controlled. Each of the switches can be controlled by the two select inputs, A and B, which determine which of the four input or output signals will be connected to the common terminal. Each channel has a separate enable input which must be high in order for the switch to be enabled. When the enable is low, all of the switches in the chip are disabled and the inputs and outputs switch will not be affected by the control inputs.

The SN74LV4051ATPWRQ1 has a limited voltage range with an absolute maximum rating of 7V, thus it is not suitable in applications that require higher voltage or higher power. The chip also has high output impedance and can’t handle large currents, making it not well suited for applications that need large amounts of current to be switched.

Conclusion

The SN74LV4051ATPWRQ1 is a four-channel analog multiplexer/demultiplexer from Texas Instruments that is ideal for applications that require switching between a group of 4 possible analog signals. It can handle both analog and digital signals and is powered by a single 1.65 to 3.6Volts of power supply. The SN74LV4051ATPWRQ1 has a limited voltage range and high output impedance, thus it is not suitable for applications that require higher voltage or higher power.
