Logic - Latches

Logic latches are digital devices used to store and retrieve data from memory. They are composed of logic gates that are connected together so that the output is determined by the state of the inputs. A logical latch is a combinational logic circuit, which, once stimulated, latches or remembers the present state of its inputs. The logic level of the latch output will be held until the latch is reset by an external reset or a logical “0” clear signal. Logic latches are usually used in memory applications, such as RAM, registers, and counters. They are also used in data transfer, data storage, and other related applications.

Working Principle of 74LVC16373ADL,112

The 74LVC16373ADL,112 is a 16-bit, edge-triggered latch with a built-in output enable. The logic level present at the data inputs (D₀–D₁₅) at the rising edge of the clock (CP) will be recognized as the latch output (Q₀–Q₁₅). The Edge-Triggered Latches guarantee monotonically increasing or decreasing output signals with a minimum of unwanted glitches.

The latch output will be enabled and available for driving connected load circuit through the output enable signal (E). When the output enable signal (E) is high, the latch output will be enabled. When the output enable signal (E) is low, the latch output will be disabled.

The Master Reset signal (MR) is used to reset the latch (Q₀–Q₁₅) and it can be configured in Synchronous (active-low) or Asynchronous (active-low) mode. In synchronous mode, the reset signal is active low and the reset is asynchronous. In asynchronous mode, the reset is active low, and the reset is synchronous.

Applications of 74LVC16373ADL,112

The 74LVC16373ADL,112 is ideal for a variety of applications, including:

• Data transfer and storage
• Memory applications such as registers, RAM, and memories
