Logic - Flip Flops

The 74FCT162374ETPVG8 is a Octal, 3.3V, Flip-flop device from Texas Instruments. It\'s a member of their 74FCT series of CMOS universal logic gates. The 74FCT series devices are a low-power, high-speed CMOS alternative to the 74LS series. The 74FCT162374ETPVG8 has eight Edge-Triggered D Type Flip-Flops, with individual Clock and Preset/Clear inputs and individual Outputs.

The Flip-Flops operation is triggered by either a rising or falling edge, depending on the Clock (CP) input. Each Flip-Flop is capable of being cleared if the Preset/Clear (P/C) input is low. The Flip-Flops are individually configured by the Master Reset (MR) input. When the Master Reset is low, every Flip-Flop will be cleared.

The Flip-Flops can be configured for positive or negative logic outputs respectively. The 74FCT162374ETPVG8 features individual outputs that are either high or low, depending on the inputs at the time of the Clock event.

Applications

The 74FCT162374ETPVG8 is chiefly utilized in asynchronous applications where external control must be applied. Commonly, this device is most applied together with sequential logic in the form of a state machine or shift register logic. Other applications include clocked register applications and multiplexed data transmission.

The octal D Flip-Flop is commonly used as a storage component to generate data sets that are used by a multitude of systems. Examples include memory storage, data manipulation across communication networks, and maintaining a sequence of data in synchronous machine architectures.

Working Principle

The 74FCT series D Flip-Flop is based on the D type latch device, a basic component of synchronous logic. Its main component is the D latch, which consists of two cross-coupled NAND gates. The 74FCT162374ETPVG8 behaves based on the data present at the Data input (D) on the rising or falling edge of the Clock (CP) signal. When the Clock signal is connected to the Data input and the Preset/Clear input is inactive the device will perform a latch-up operation. This will store the data bit present in the Data input until the next transition occurs in the Clock signal.

Additionally, there are two other key input signals, the Master Reset (MR) and the Preset/Clear (P/C). The Master Reset is a global reset that ties all the Flip-Flops outputs to minimize power consumption when no data is being processed. Preset/Clear is used to immediately reset the Flip-Flops when required.

Conclusion

The 74FCT162374ETPVG8 is a Flip-Flop device from Texas Instruments\'s 74FCT logic series. It features eight edge-triggered D type Flip-Flops with inputs for clock, data, master reset and preset/clear. It can be used as a storage component to generate data sets used by a variety of systems, such as communication networks and synchronous machines.

Its operation is based on the Data (D) input, being latched onto the output on the transition edge of the Clock (CP) input. The Master Reset (MR) and the Preset/Clear (P/C) inputs provide additional control by setting or clearing any Flip-Flop output when required.
