SN74HC4851PW Analog Multiplexer/Demultiplexer

The SN74HC4851PW from Texas Instruments is a versatile single-ended 8-channel multiplexer/demultiplexer. This integrated circuit (IC) is designed to provide high-performance analog signal switching for a wide range of applications, including data acquisition systems, signal routing, and communication systems. It is part of the HC family, which is well-known for its high-speed CMOS technology.

The device features a wide analog input voltage range from 2 V to 6 V and a low ON-state resistance, typically around 70 ohms, which ensures minimal signal distortion. It operates over a broad temperature range of -40°C to 85°C, making it suitable for industrial applications. The SN74HC4851PW also boasts a low power consumption, which is critical for battery-powered and energy-efficient designs.

With its single-ended configuration, the SN74HC4851PW allows for the connection of up to eight inputs to a common output, or vice versa when used as a demultiplexer. The selection of the desired channel is controlled by three digital select inputs (S0, S1, and S2), allowing for easy interface with microcontrollers or other digital logic.

The SN74HC4851PW is offered in a 16-pin TSSOP (Thin Shrink Small Outline Package) that is optimized for reduced space on printed circuit boards. This package is RoHS compliant and is designed for surface-mount technology (SMT), providing a compact solution for modern electronic systems.

Key features of the SN74HC4851PW include:

• 8-to-1 channel configuration
• Wide operating voltage range (2 V to 6 V)
• Low ON-state resistance
• Low crosstalk between switches
• Low off-state current
• Extended industrial temperature range (-40°C to 85°C)
• 16-pin TSSOP package for space-saving applications

Overall, the SN74HC4851PW is a reliable and efficient solution for designers looking to multiplex or demultiplex analog signals in their electronic systems, while maintaining signal integrity and minimizing power consumption.
