The MM74HCT245SJ is categorised as a logic-level device; that is, it is used to set and buffer multiple digital signals. It operates at very low power levels, which is why it is popular amongst applications where low-voltage signals are present, such as in data transfer, instrumentation and control systems, digital communication circuits and more.

The MM74HCT245SJ, a quad non-inverting buffer, is a type of CMOS logic IC (integrated circuit) that consists of four independent drivers that receive data and route it to output pins. Each driver has a direction control line (DIR) which allows input data to be selectively defined as either input or output. Output current is capable of sinking/sourcing up to 32mA than can drive up to 15 TTL/CMOS logic devices.

The logic supply voltage for the MM74HCT245SJ can range from 2V to 6V, and it is provided with TTL type inputs and outputs. Additionally, it features low power consumption and the outputs can be used in high-speed applications.

A key feature of this IC is its active low DIR control line, with logic \'0\' enabling data transmission in the forward direction and logic \'1\' for reverse direction. Data is buffered in both directions and the active high ENABLE input line allows the IC to function as two separate two-bits buffers. A logic level \'1\' disables the IC by preventing data transfer, while a logic level \'0\' enables data transfer.

The MM74HCT245SJ is used in a variety of applications in the field of communications, such as modems, laser printers, cable modems, and more. It is also ideal for systems incorporated into an automobile, such as anti-lock brakes, traction systems, and vehicle suspension systems.

In most cases, the MM74HCT245SJ is used to transfer data from multiple components to a microcontroller or a peripheral device. The IC can be used in various bi-directional data transfer and buffer applications, as it can provide bus/data line isolation and protection for data transferring in both directions.

The MM74HCT245SJ operates using CMOS logic, which has a significant advantage over TTL logic with regard to its very low power consumption. Furthermore, CMOS technology offers immunity to noise, fast switching speeds, higher packing density and compatibility with a range of CMOS-compatible systems.

The MM74HCT245SJ is an essential part of any circuit implementation requiring a lower-powered, higher-performance solution. It offers reduced power utilization at a lower cost and is a reliable four-bit buffer solution for applications requiring two-way data transfer.
