Logic-Signal Switches, Multiplexers and Decoders are widely used in a variety of applications, such as data acquisition, memory storage and analog-to-digital conversions. SN74LVC138ADE4 is a quad 2–input multiplexer/demultiplexer that provides select signals for two channels of data and 4-bit data paths. This device consists of four 2–input multiplexers/demultiplexers and uses the select signal from the selection input lines to control the channel selection. This device is ideally suited for low-voltage, low-current applications and operates with power-supply voltages of 2.5 to 3.6V and at temperatures ranging from -40°C to +85°C.

The SN74LVC138ADE4 is a 4-bit, 2-channel multiplexer/demultiplexer with multiplexed address and data lines. The multiplexing is performed on the data lines while the selection is determined by the address lines. The multiplexer/demultiplexer configuration allows for four 2-input lines, two 4-bit data paths and two 4-bit selection lines. Each 2-input line is selected by a 2-bit address line to produce a 4-bit output. The address lines are connected to a bus, which is connected to all the 2-input lines. The data lines are used to transfer the data from the multiplexer/demultiplexer.

The operation of this device is very simple. The address input lines are used to provide the select signal for the corresponding data line. The multiplexer/demultiplexer then uses the address lines to select the appropriate data line to output its data. The address lines also control the direction of data transfer. The multiplexer/demultiplexer can be used to transfer data in either direction, depending on the values of the address lines.

The SN74LVC138ADE4 is a versatile device and can be used in a wide range of applications. It can be used in data-acquisition systems, to multiplex digital signals and to interface digital circuits with analog inputs. It can also be used in memory storage applications, in analog-to-digital conversions and to provide fault-tolerant interconnects in distributed systems. It is also suitable for controlling LEDs and for use as a data selector in a wide range of multiplexers and demultiplexers.

The SN74LVC138ADE4 is a cost-effective device offering high levels of performance due its low-voltage capability, low-current requirements, and high-speed switching. The device also provides excellent noise immunity, thermal stability, and high impedance to reduce noise coupling. Its wide operating temperature range also makes it suitable for industrial and automotive applications.
