The 74LCX138SJX, which falls under the category of logic-signal switches, multiplexers and decoders, is a logic device that provides several useful functions related to routing of data signals, for example, enabling the decoding and selection of certain inputs and outputs operating at low-voltage, high-speed CMOS. This device is capable of performing 1-of-8 decoding and also can be used to select 1-of-16 address lines, depending upon its configuration. In addition to this, it can be used to act as a multiplexer, by allowing a single pin to serve as both an input and an output.

At the core, the 74LCX138SJX works on the principle of NAND logic and is comprised of three NAND gates at each input and output. This allows it to use three separate data inputs to determine which of the output signals will be activated. The lines of the input register are trusted to be low-level signals, meaning that they have to have been pulled down to 0 before they can be read. In terms of the output lines, these are said to be high-level signals and are usually tied up high to 3.3V.

The 74LCX138SJX is designed to be used in an array of applications, such as in automotive systems, including those related to instrumentation, conveying, vacuum, breakers and relays. It is also popularly used in video game consoles, particularly gaming chairs, as well as in HDD applications, to control the movement of positioners and actuators. Furthermore, it can also be utilized for digital control signals, such as those linked to PC boards, LCDs, and LEDs.

The 74LCX138SJX provides a number of advantages over other logic devices, mainly because it can process multiple signals without having to use extra circuitry. It has extremely low power consumption, with a quiescent voltage of only 0.6V and typical supply current of only 3.5mA at 3.3V. Its speed is also competitive, as it can perform low-level NAND operations at up to 26MHz, while also providing minimal latency.

Some of its key features include 8-bit input and 8-bit output buffers, as well as distinct enable lines for the upper and lower halves of the output register. The device also features oscillation prevention circuitry and open-drain inverters, giving the designer further options for advanced designs. Furthermore, it is robust in terms of power supply noise, with up to 35mA of peak current delivery.

Overall, the 74LCX138SJX is an incredibly versatile and powerful logic device, able to provide a single output from 8 different inputs, or select one address line from 16. It is designed for low-voltage applications, such as those usue in automotive, video gaming, imaging and HDD systems, and can process multiple signals with extremely low power consumption, high speed, and minimal latency.
