Flip-flops are the most versatile logic gate element, and the 74LVC16374APAG is one of the newer most popular models. It is a 16-bit wide dual-edge triggered flip-flop with a single clock input and a clear control input. The device is designed for low-voltage, high-speed applications.

application field

The primary applications of the 74LVC16374APAG include synchronization, filtering, memory, and address resynchronization. Synchronization occurs when data must be aligned at two or more clock edges in order to use in a digital system. Filtering allows the passage of data into a system while rejecting unwanted noise. Memory stores data and address resynchronization keeps the data in synchronization with multiple transmission signals.

Working Principle

The 74LVC16374APAG flip-flop is based on the two-phase, non-overlapping clock design. This means that the clock signals must go from low-to-high, stay high for a minimum period of time, then go from high-to-low, and stay low for a minimum period of time. This allows the data to be sampled when the clock is at its peak, also known as the “non-overlapping” condition.

The device is designed for applications requiring low power dissipation. It features a VCCI (internal power supply) and a VSSI (internal ground) that are brought outside the device so that the VSSI line is independent from any other VSS line. This allows each device to be configured differently.

The device also features an edge-activated data capture pin that can be used to sample the data when the clock goes from low-to-high. The data-capture pin can also be used to hold the data until the next rising edge of the clock. This allows the data to be captured without the need for an external latch.

The device also features an active low clear input that can be used to reset all of the outputs to their low state. This feature can also be used to synchronize the outputs when the clear input is toggled.

Conclusion

The 74LVC16374APAG is the ideal flip-flop for applications requiring low power dissipation and high speed operation. The wide input and output buffers allow the device to be used in both synchronous and asynchronous data transfer systems. The dual-edge triggered nature of the device allows for the data to be sampled when the clock is at its peak. The device also features an active low clear input that can be used to reset the outputs or to synchronize data. With these features, the 74LVC16374APAG is an ideal choice for logic applications.
