The 74LV138DB,112 is a logic signal switch, multiplexer and decoder in one. It is a three-to-eight line decoder/demultiplexer with an address latch, active LOW output enables, and three select inputs. The 74LV138DB,112 offers high performance and advanced features, making it an ideal choice for a variety of applications.

The 74LV138DB,112 has three data inputs (A0, A1, and A2) and eight output enables (OE1, OE2, OE3, OE4, OE5, OE6, OE7, and OE8). The device has three select inputs (S 0, S 1 and S 2) that control the data flow. When S2 and S1 are LOW and S0 is HIGH, the device is in decoder mode, and the active LOW output enable is asserted when A0, A1, and A2 match the state of the select inputs. When S2 is LOW and S1 and S0 are HIGH, the device is in multiplexer mode and the outputs are disabled.

The 74LV138DB,112 features an address latch (Lat) that is used to remember the address inputs when the control signals S2, S1 and S0 are activated. The address latch is enabled when Lat is LOW and is disabled when Lat is HIGH. When in multiplexer mode, the address latch is enabled by placing the control signals in their active state and then bringing S1 and S0 LOW to facilitate data selection from the address inputs. The 74LV138DB,112 is equipped with an active LOW output enable (OE) that is enabled when S2 and S1 are LOW and S0 is HIGH. The output enable is disabled when S2 and S1 are HIGH and S0 is LOW.

The 74LV138DB,112 has many applications in industrial, automotive and consumer products. It can be used in data processors, address decoders, memory access address selectors, programmable/adjustable building block circuits and control logic to replace many small parts. It can also be used in power supply circuits, LED and display drivers, LED light show controllers, LED character displays, automotive electronics, disk drive circuits, clock circuits, communication equipment and many other applications.

The 74LV138DB,112 is a valuable, versatile and powerful device for adding intelligence to all kinds of design applications. It is designed for high-speed operation and has low power consumption, making it an attractive solution for a wide range of applications. Its advanced features and reliable performance make it an ideal choice for engineers looking for an effective solution for their challenging design requirements.
