CD74HC74MT Datasheet/PDFFlip-flops are basic building blocks in digital systems and are used for temporary data storage.The CD74HC74MT is a D Flip-flop integrated circuit (IC) that is constructed with the MOS technology.It is suitable for a wide range of applications from synchronous design to sampling and data storage.
The CD74HC74MT is a low-power, dual-flip flop device with D type flip-flop circuits. It is designed for asynchronous operation, which enables it to accept and store data on two rising edge clock signals which are offset in time, thus providing a desirable interface to many types of micro-controller and logic systems. The signals entering the logic gate are first buffered through two sets of Digital Input Buffers and then transferred directly to the internal flip-flops.
The CD74HC74MT application field consists of logic systems that require storage of digital data, and the central processing unit (CPU) interfaces of computers, microcontrollers, etc. It is also used in digital signal processing and battery-backed memory systems. The key features of the CD74HC74MT are: low power consumption, 20-pin DIP package and asynchronous input/output.
The main operating principles of the CD74HC74MT are based on the D type flip-flop circuit, which is a basic building block in digital systems, as mentioned earlier. This circuit enables the transfer of data bits from one point to another in a circuit without the need of an additional element, such as a wire, to hold the data between the two stages. Basically, the circuit works in the following way: when a data bit is presented to the input of the circuit, the circuit stores the data bit in the internal register, and the output of the circuit will have the same data bit that was presented to the input. Additionally, the circuit provides a set (1) or reset (0) output, depending on the state of the internal register.
The CD74HC74MT also includes a clock pin, which is used to transfer the data from the input to the output.When this pin is active, the data at the input will be transferred to the internal register, and the output will update with the data that was presented at the input. When the clock pin is inactive, the output will be held at the last value that was stored in the internal register.
Furthermore, the CD74HC74MT contains two control pins, RD and RST.The RD pin is used to read the data from the internal register. When this pin is active (high), the output will show the data stored in the internal register. The RST pin is used to reset the internal register to zero (0) when it is active (high).
In summary, the CD74HC74MT is a low-power, dual-flip flop IC that is suitable for a wide range of applications from synchronous design to sampling and data storage. It is constructed with the MOS technology and features asynchronous input/output, low power consumption, and a 20-pin DIP package.Its D type flip-flop circuit enables the transfer of data bits from one point to another in a circuit, and the clock pin is used to transfer the data from the input to the output. The RD and RST pins are used for reading and resetting the internal register, respectively.
