It can also be used to implement complex logic functions such as state machines and simple microprocessor-based systems. It is also an excellent choice for implementing high-speed digital signal processing (DSP) applications.

Working Principle

The 74ALVT16821DL uses a positive-edge triggered D-type flip-flop which allows data to flow through the device from one clock to the next. Data is loaded into the flip-flop on the rising edge of the clock signal, and the output data is latched on the falling edge of the clock pulse. The design allows the output data to be stored either in the set or reset state until the clock signal transitions again. The flip-flop also has a clock enable input (CE) which can be used to control the operation of the flip-flop. When the CE is low, the flip-flop is disabled and all signals on the data inputs are ignored. When the CE is high, the flip-flop is enabled and all data on the inputs is latched on the rising edge of the clock signal.The device also features power-down control which allows the device to remain in a low-power, quiescent state when not in use. The power-down control feature allows the device to be powered down when not in use and turned back on again with a single command.The 74ALVT16821DL is an excellent choice for applications requiring high-speed logic operations and complex logic functions. Its high speed, low power consumption and wide operating voltage range, make it an ideal choice for a variety of system control and digital logic applications.
