The NLV74ACT138DR2G is a quad two-line-to-four-line decoder demultiplexer from Fairchild Semiconductors’s very famous 74ACT Logic family. It is a dual 4-line decoder/demultiplexer, which is capable of routing two single bit-wide data signals (A0 and A1) to four separate outputs (Y0-Y3). The trigger input (G) is used for selecting either the four-line (when low) or two-line (when high) demultiplexing feature.

The NLV74ACT138DR2G is commonly used in digital systems where a certain signal needs to be routed to one of four different sources selectively. It can be used in various scenarios such as in timing and data-recovery applications. It is used to drive outputs with a single data or clock line and to access one out of four storage locations using multiplexing technique. Also, it is used in communications systems in order to direct one input to one of the four separate paths.

The working principle of the NLV74ACT138DR2G consists of decoding the two binary-coded inputs (A0 and A1) and selecting within the two stable states. If the trigger input (G) remains in the low state, the two separate data inputs (D0 and D1) will feed the four outputs (Y0-Y3). When the G input is high, the input data of D0 and D1 will be divided equally and fed to the four outputs (Y0-Y3).

The NLV74ACT138DR2G includes input signals of two binary-coded inputs A0 and A1 and four outputs Y0-Y3 that can be used as either active HIGH or active LOW based on the state of the input signal G. The circuit also includes active LOW enable (EN) inputs, which are used to place the device in either active or standby states. When the EN inputs are LOW, the outputs become HIGH. Conversely, when the EN input is high, the device will be disabled and all outputs will become LOW.

The NLV74ACT138DR2G has various advantages over the other devices, such as its availability in various configurations, including those using multiple chips or integrated into one package, which allows the user to best suit their circuit requirement and reduce the costs associated with extra components. Also, the device’s high speed operation makes it ideal for high speed logic applications, and its low power consumption provides a great deal of power efficiency.

In summary, the NLV74ACT138DR2G is an excellent solution for routing two single bit-wide data signals (A0 and A1) to four separate outputs (Y0-Y3). It is quick, efficient, and is the perfect solution for timing and data-recovery applications, communications systems, and multiplexing techniques. Its range of available configurations and its low power consumption, make the NLV74ACT138DR2G a great choice for logic applications, whether integrated or not.
