SN74HC4851N is an 8-to-1 analog multiplexer/demultiplexer which is utilized in many analog signals switching circuits. It enables selection of two independent channels that are passed to output based on the digital input states. It is consisting of 8 double-pole double-throw switches (DP3T) which allow 8 analog inputs to be switched to one common output line.

It belongs to the family of 74HC logic IC, delivering high-speed capability. It is a dual-ported device, featuring 2 ports to enable bidirectional communication between two platforms or nodes within a circuit. The device is suitable for interfacing analog and digital elements within a system.

The SN74HC4851N is widely used in UHF and HF band circuits, particularly in antenna switching. It is also very useful for circuit applications that require multiple selections from a single analog input line. This kind of switching circuit simplifies the system design and lowers the cost. The device has three different modes: 1. Analog switches; 2. Multiplexers; 3. Demultiplexers.

The SN74HC4851N works based on the mathematical operations of combinatorial logic. Its switch logic is controlled by two active low enable pins, with which two multiplexed channels can be selected from 8 analog input signals. Its internal structure is based on an 8-channel, 1.6V to 5.5V CMOS multiplexer/demultiplexer.

The outputs of the device can be used as a power control source or a logic source to control other devices. It also can be used to coordinate the control signals between various system blocks. The switching speed of the SN74HC4851N is relatively fast and its power consumption is very low. Additionally, the device is available in both 8-pin and 7-pin packages.

The SN74HC4851N can be used in a wide variety of applications such as switching audio signals, logic control, data acquisition systems and display systems for digital control. It is also used in radio frequency (RF) switching. This kind of device is used in applications that require analog signal switching from a few to many links, such as the ones utilizing data conversion and signal processing.

SN74HC4851N is a highly reliable and robust interface with many advantages over traditional analog switches and multi-channel multiplexers. It has exquisite design and requires less current for operation. It is also RoHS compliant, making it simpler for electronic designers to include it in their system.
