Logic - Flip Flops have many applications and come in various designs. The N74F374DB,118 is a typical dual D-Type flip flop with a clock enable. It is used in a variety of projects, from embedded systems to off-the-shelf electronics. This article explains the features and applications of this flip flop and its working principle.

The N74F374DB,118 is a type of dual D-Type flip-flop designed with a clock enable. It has two input and output stages, with each input stage having two data inputs and a single clock enable. The output stages have a single data output and an asynchronous reset. When the clock enable input is low, the data outputs are held in their present state. When the clock enable is high, the data in the inputs are transferred to the outputs.

The main feature of the N74F374DB,118 is its low power consumption. It only uses 5 mW of power, making it ideal for use in embedded systems. Additionally, its power consumption remains the same regardless of the clock frequency, making it suitable for use in a variety of applications.

Various applications can benefit from using the N74F374DB,118. One application is in pulse-width modulated (PWM) applications, where the flip-flop can be used to store the duty cycle of the PWM signal, ensuring consistent output even when changes in the duty cycle occur. The flip-flop can also be used in high-speed data acquisition systems, as it is able to store data as it passes through the data inputs. Additionally, the flip-flop can be used as a latch in clock synchronous designs, allowing control logic to be coordinated with the clock signal.

The working principle of the N74F374DB,118 involves the transfer of data from the input stage to the output stage when the clock enable is high. When the clock enable goes low, the data in the input stage is held in its present state, and the output remains unchanged until the clock enable goes high again, at which point the data is transferred to the output.

When the reset input is high, the output stage is reset and the data is held in a known state. This ensures that any erroneous data is cleared from the output stage, as the data will remain at the known state until the reset input is low.

In summary, the N74F374DB,118 dual D-Type flip-flop is a low-power and reliable logic device. Its features make it suitable for a range of applications, including PWM systems, high-speed data acquisition applications, and clock synchronous designs. Its working principle involves transferring data from the input to the output stage when the clock enable is high, while its reset feature ensures that data is held in a known state.
