The SN74LV4051ARGYR is a high-performance analog switch IC. It belongs to the family of switch devices known as Interface – Analog Switches, Multiplexers, Demultiplexers. It is a 3-state multiplexer featuring improved ESD protection and JESD 12-5-compliant chip-to-chip communications. This multiplexer device is optimised for low power operation, making it ideal for battery-powered applications.

The SN74LV4051ARGYR is a 4-channel multiplexer – it serves as a single port allowing up to four single-bit signals to flow to one. It has two control inputs, a common select (CX) line and an individual select line (S1, S2, or S3). The CX line is responsible for selecting either input A or input B, while the individual select lines (S1, S2, S3) are responsible for selecting each of the respective inputs.

The SN74LV4051ARGYR features the standard configuration of two 8-bit data buses – A and B. Each bus can be switched between either input A or input B based on the state of CX. If CX is set high, the A bus will be connected to input A, and the B bus to B. If CX is set low, the A bus will be connected to input B, and the B bus to A.

The device also boasts 3-state outputs, allowing two full-8 bit buses to be switched. When the CX line is driven LOW, one output state is disabled and the multiplexer is set in the Tri-state buffer mode. The 3-state buffer can be used to drive high-impedance outputs for data buses requiring larger numbers of connections.

In its basic configuration, the SN74LV4051ARGYR is designed to operate in the range of 5.5V to 3.3V. It is capable of switching up to 2.4MHz in logic threshold from 1.2V at 25°C. The operating temperature range for the device is from -40°C to 85°C. Minimum on-state resistance is 10 ohms.

The SN74LV4051ARGYR finds use in a range of consumer electronics, consumer-market equipment, data buses, and sensing and measurement systems. It is useful wherever analog signal switching and multiplexing is required in low-voltage, high-current signal routing applications. It features built-in protection against ESD, making it an ideal choice for low-power application circuits.

In summary, the SN74LV4051ARGYR is an ideal choice for signal routing applications that require multiplexing and analog switching. It is a 3-state multiplexer with improved ESD protection, and is designed for low-power operation. It operates at low voltages and high currents, and is suited for a variety of consumer and industrial applications.
