Working Principles

The SN74ALVTH16374DL is a D-type flip-flop with 3-state outputs. It stores and transfers data based on clock signals. When the clock input (CP) transitions from low to high, the data present at the D0-D15 inputs is latched and stored in the flip-flop. The stored data can then be accessed through the Q0-Q15 outputs.

The output enable (OE) pin controls the state of the outputs. When OE is low, the outputs are active and reflect the stored data. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus.

The master reset (MR) pin resets the flip-flop when activated. This sets all outputs to a low state.

Detailed Application Field Plans

The SN74ALVTH16374DL is commonly used in various applications, including:

1. Data Communication Systems: Used for data buffering and synchronization in high-speed communication systems.
