Logic circuits are building blocks used to construct various digital devices, systems and different types of industrial control networks. The logical operation is the basic concept behind all types of digital integrated circuits. The MC74LCX157DTG is an integrated circuit used for logical operations. The device is an 8-bit multiplexer/demultiplexer with two-sided logic control and low voltage logic levels. It is a versatile device with an easy-to-use and cost effective solution for most logic switching applications.

Applications

The MC74LCX157DTG provides a reliable switching solution for a wide range of applictaions. It can be used in a variety of industrial control networks that require signal switching. It is also a great choice for digital video and audio signal routing. The device can be used in memory datapath multiplexing and memory bus control circuitry, digital video designs and embedded systems. It is also suitable for logic signal switching in consumer electronics, digital cameras, MP3 players and digital video recorders.

Working principle

The MC74LCX157DTG consists of eight data lines and eight control input lines. The eight data inputs are connected to the eight data output neurons, with each data line controlled by a single control line. When the control line is set to a logical “1”, the corresponding data line is enabled and the output neuron is set to the same voltage level as the input. When the control line is set to a logical “0”, the corresponding data line is disabled, and the output neuron is set to a different voltage level than the input.

The device provides three Enable Control inputs, which can be used to select individual data lines for multiplexing, or deselect the entire device for testing purposes. The Enable Control inputs can also be used to latch data inputs and outputs, or to store data. The device is designed to provide fast and efficient signal switching, and is designed to be used with CMOS logic circuitry.

The MC74LCX157DTG provides a versatile and cost effective solution for high speed switching and digital signal routing. The device is easy to use, and provides a reliable and robust solution for many digital applications, making it a popular choice for many digital designers.
