74LVC2G66DC,125 belongs to the Interface - Analog Switches, Multiplexers and Demultiplexers. It is a low voltage CMOS logic Dual 2-Channel Multiplexer/Demultiplexer with 2 Enable controls. This device includes two 2-channel multiplexer/demultiplexers with common inputs and outputs and two enables per section.

In its application field, the 74LVC2G66DC,125 device is used in the control and distribution of digital control signals such as memory address, data buses and control signals. It is also used to switch data between two independent systems. The device offers a wide range of flexibility in highly parallel electronics systems.

The working principle of the 74LVC2G66DC,125 is very simple. The two G-select inputs S1, S2 determine the direction of data flow with LOW to HIGH logic level transition. The Enable (E1, E2) inputs are used to enable or disable an individual 2-Channel Multiplexer/Demultiplexer section. When a 2-Channel Multiplexer/Demultiplexer section is disabled, its OFF-state, output impedance levels are extremely high.

All inputs are equipped with protection circuits against static discharge and transient excess voltage which protects the circuit from damage at power up and power down. Outputs are ultra low power consumption types, which give users significant power savings and also contribute to a reduction of power dissipation.

The 74LVC2G66DC,125 is designed to meet rigorous speed and power requirements with low power dissipation. It has a high speed of -3.5ns typ. low quiescent current of 0.6µA and low input and output leakage currents of 1.0µA at +25°C. Its operating voltage can range from 2.0V to 5.5V and the storage temperature range covers from -55°C to 125°C.

In conclusion, the 74LVC2G66DC,125 is a low voltage CMOS logic Dual 2-Channel Multiplexer/Demultiplexer with reliable performance and low power consumption. It is suitable for application such as control and distribution of digital control signals and for switching data between two independent systems.
