Logic – Flip Flops

Flip flops are types of binary storage elements used in any type of digital switching system. In the simplest form, a flip flop is a digital circuit that can store one bit of information. Flip flops are built using combinational logic as a means to introduce data into the circuit and then something known as a gated latch, or a clock, that determines when the stored value will take place. There are different types of flip flops such as RJK, D, JK, T and SR. Each of these types has its own particular working principle, and one of these types is the SN74LVTH273DWG4.

SN74LVTH273DWG4 Application Field and Working Principle

The SN74LVTH273DWG4 is a dual D-type flip flop, or a simple clocked-bits register, which is used for storing two bits of information. It consists of two data latches, which are triggered by a clock signal. It is commonly used in applications requiring data storage where the data is only updated when the clock signal is triggered. The SN74LVTH273DWG4 has two enable/inhibit [EN/IN] inputs, a clock (CLK) input, two data (D) inputs, two complement data (D) inputs, and two outputs (Q, Q’).

The D inputs are the inputs that provide the data that is to be stored in the register. The EN/IN inputs are the inputs that are used to determine whether the D inputs are enabled or inhibited. When the EN/IN inputs are LOW, the outputs will be the same as the D inputs. When the EN/IN inputs are HIGH, the outputs will remain the same regardless of the inputs. The clock is used to determine when the data is transferred from the inputs to the outputs.

When the clock is LOW, the data that is present at the D inputs is held in the flip flop and is not transferred to the outputs. However, when the clock is HIGH, the data is transferred from the data inputs to the outputs. Therefore, the data present at the D inputs is only updated when the clock signal transitions from LOW to HIGH.

Conclusion

The SN74LVTH273DWG4 is a dual D-type flip flop that is used for storing two bits of information. It consists of two data latches that are triggered by a clock signal. The D inputs are the inputs that provide the data to be stored, and the EN/IN inputs are used to determine whether the D inputs are enabled or inhibited. The data present at the D inputs is only updated when the clock signal transitions from LOW to HIGH.
