The MC74LVX573M is a multi-function at-speed static latch from Fairex. It carries a robust design which enables a wide range of applications in data acquisition, signal processing, and logic gates. This feature makes the device useful for a variety of applications. The MC74LVX573M is a high-speed logic device with a latch controlled by two inputs. It has an active-high asynchronous preset and reset, and active-low strobe input. The features of MC74LVX573M allow it to be applied in a variety of situations as a fast static memory device, providing logical solutions to various problems.

The MC74LVX573M is a static latch that consists of two latches controlled by two inputs. It has an active-high asynchronous preset and reset, and an active-low strobe input. It is designed to be used in data acquisition, signal processing, and various logic gates. This device is powered by a 5 V supply and can operate over a wide range of temperatures, from -40°C to 85°C.

Working Principle

The device’s working principle is based on the action of two serially connected latches. The latches are controlled by two inputs, P and S, along with a single active-low strobe signal. When the signal S is at low level, the output of the first latch (Q) will hold the state of input P, which makes it possible to save the state of the signal P even if it is changing during the period when S is low. The second latch (Qbar) will hold the same state as input P, but it has an inverted logic meaning that when P is high, Qbar output will be low and when P is low, Qbar output will be high.

The switch of the triggering signal S to high level after it has been low before will change the state of the latch and will make the output of the first latch (Q) match the state of the input P at that time. This process is known as “latching” and it is how the MC74LVX573M receives its input and stores it in the output. The second latch (Qbar) acts as an inverter, allowing for versatile logic implementations. The asynchronous active-high P-bar and R-bar signals on the device also allow for easy reset/preset operations.
