Logic - Flip Flops

The 74HCT374DB,118 is a logic level flip flop device, part of the 74HCT logic family. It has two inputs, a data pin and a clock pin, and two outputs, a Q and not Q (Q’). It is designed to store digital bits of data and is widely used in computer memory and device circuits to latch and hold binary information.

Application Field

This flip flop device can be used in the design of digital systems in a variety of different ways. It is capable of storing bits of data as well as providing a source of clocking for other components in a system. The fact that it uses low voltage logic levels makes it ideal for a wide range of systems such as digital control and industrial process control equipment.

It can also be used to create shift registers and state machines. In addition, this flip flop can be used to create counters, shift registers more quickly than the more traditional discrete logic gates, and can interface with data buses such as I2C, UART and SPI. They can also be used in memory applications, such as RAM, ROM, and EEPROM.

Working Principle

The 74HCT374DB,118 works on the principle of data storage upon the arrival of a clock edge. When a data bit is inputted into the logic level flip flop on a data pin the data is stored for later use. The stored data will stay stored until a clock pulse is applied, typically from a clock input or from a different source of clocking, which causes the data to be stored and then transferred to the output pins.

Controlling the flow of data with the flip flop is done by the use of two inputs, a data pin and a clock pin. When the data pin receives a logic 0 or logic 1, it is stored until the clock pin receives a logic 1, which causes the stored data to be outputted. The data stored and outputted depends upon the logic level of the data pin, either 0 or 1.

The flip flop can be used as a source of clocking in systems, where the clock pin is connected to an external source of clocking, often from a system clock. The clocking from the clock pin is then propagated through the system, causing the flop to store and transfer the data output, making it available for consuming components.

The 74HCT374DB,118 can also be used in other ways, such as when the data pin is connected to receive data from an external source. With this setup, the data fed into the data pin can be outputted with the clock input, allowing for the quick transfer of digital data.

The versatile 74HCT374DB,118 makes use of two distinct modes of operation, the data transition latch (DTL) mode and the master-slave J-K flip flop. The main difference between these two modes lies in the timing of the data bit transition. In the DTL mode, the data bit transition takes place during the falling edge of the clock while in the J-K flip flop the data bit transition takes place during the rising edge of the clock.

The 74HCT374DB,118 is an extremely versatile and powerful logic level device, capable of storing and transferring bits of data with a single clock edge. It can be used in a variety of applications in digital systems, from bus interfacing to memory storage. Its wide range of programming options make it suitable for a variety of uses.
