Introduction

The SN74LV4051AQPWRQ1 is an interface device used for analog switching, multiplexing, and demultiplexing applications. This device is a single-pole, eight-position multiplexer/demultiplexer, operated from a single logic supply. It is available in a variety of packages and offers low power consumption levels. The SN74LV4051AQPWRQ1 is ideal for high-speed multiplexing and data routing applications with highly accurate switching.

Application Field

SN74LV4051AQPWRQ1 is ideal for data routing and communication applications. It can be used in various settings involving analog switching such as intensity modulation, video routing, and video color control. The device can also be used in data storage, conversion, and transfer applications such as phase-locked loop and frequency synthesizers.The device is also suitable for filtering and attenuation applications, as well as for frequency-translating and receiver select applications. It can be used in systems with up to eight multiple channels, including mobile communication networks, radio-frequency receivers and transmitters, ADCs and DACs, and frequency synthesizers.

Working Principle

The SN74LV4051AQPWRQ1 is a single-pole, 8-position multiplexer/demultiplexer with two active-high select inputs, S0 and S1, and eight independent input/output (I/O) channels labeled A, B, C, and so on. The active-high enable input (G) turns the device ON when asserted by application logic.The multiplexer/demultiplexer is used to select one of the eight I/O channels to be enabled at any given time. This is accomplished by the combination of S0 and S1, which select the I/O channel to be enabled based on the importance assigned to each S0, S1 combination. The enables signals will activate the I/O for the designated channel only.The SN74LV4051AQPWRQ1 can also be used as a 1-to-8 demultiplexer by using the enable signal G as the input. In this scenario, the selected information is latched on the selected input/output (I/O) when G is asserted. The data is propagated to the output line at the same time that G is asserted.
