SN74HC4851PW

Introduction

The SN74HC4851PW is an 8 channel analog multiplexer/demultiplexer IC manufactured by Texas Instruments. It is a part of the HC family of logic ICs developed by TI, which combines both low power usage with high performance standards. The SN74HC4851PW is also available packaged in different formats, such as TSSOP and SOIC. This article will focus on the features, application field and working principle of the SN74HC4851PW.

Features

The SN74HC4851PW is a 8-channel analog multiplexer/demultiplexer capable of data transmission over a single line. The device operates on a single supply voltage range from 2V to 6V, and can switch all of its channels in less than 16ms, meaning that it is capable of high speed data transfer as well. In addition to this, the device is designed to be extremely low power, consuming only 12 μA, meaning it is suitable for battery powered applications. The device also features a three-state output, meaning that it can be used to drive three-state buses. Finally, the device is provided with an enable pin. When this pin is asserted low, it turns off all channels.

Application Field

Due to its low power usage, high speed and multiplexer/demultiplexer features, the SN74HC4851PW can be used in a variety of applications. It can be used as a analog voltage selector in order to optimize power usage, or as a fast data transmission device. The device can also be used in battery powered applications, as its low power usage allows it to work for extended periods on a single charge. With its three-state output, the SN74HC4851PW is suitable for bus transmission, and can be used to build reliable communication networks. Finally, its enable pin makes the device suitable for systems that need to be turned on and off.

Working Principle

The SN74HC4851PW is an 8 channel analog multiplexer/demultiplexer that is able to transmit data over a single line. It operates on a single supply voltage range from 2V to 6V, with a power consumption of only 12 μA. The device has two input pins, one for data and one for selection. By setting the selection pin to one of the 8 channels, the data will be transmitted to the output. The enable pin can be used to turn off all channels. The device will then be able to switch between different channels at speeds of less than 16ms.

Conclusion

The SN74HC4851PW is an 8 channel analog multiplexer/demultiplexer manufactured by Texas Instruments. It is low power, high speed and has a three-state output, making it suitable for a variety of applications such as voltage selection, data transmission, reliable communication and battery powered devices. With its enable pin, it is possible to turn off all channels at once. The working principle of the device is simple, setting the selection pin to one of the 8 channels will transmit the data to the output.
