MC74AC573DTR2G Integrated Circuits (ICs)

The MC74AC573DTR2G logic latch is an integrated circuit (IC) of type D-type flip-flop, belonging to a larger family of products related to both latches and logic integrators. It is widely used in industrial, automotive and consumer applications for various purposes.

Generally speaking, a flip-flop is an element which stores one bit of information and provides the user with an ability to access this information at any time. This circuit plays an important role in digital systems, as it can store a single value in its memory. Latches, on the other hand, are devices used to keep a certain number of bits in a certain state.

The MC74AC573DTR2G logic latch is a two-stage, buffered, direct-drive latch with a propagation delay of 16 nanoseconds. It has a separate active-low enable (E) input and a reset (R) input. An edge-sensitive clock (C) pin triggers the latch to transition from one state to the other depending on two input data pins D and D.

The MC74AC573DTR2G’s primary purpose is to allow the device to store a value, either high or low, when triggered by the clock C input. This set of inputs allows it to be used in any circuit in need of storing data and retrieving it as needed. Its applications include:

• Data memory in digital systems
• Transmission gate for frequency division
• Flip-flop for clocked logic systems
• Asynchronous back-up system

The working principle of the MC74AC573DTR2G is based on the operation of the latch with asynchronous enable and reset. It is triggered by the edge-sensitive clock (C) pin and it consists on three operating stages:

• The enabled stage
• The hold stage
• The reset stage

In the enabled stage, the enable pin (E) is active. When the rising edge of the clock pin (C) is detected, the logic state of the two data input pins (D&D ) is determined, and the output pins Q and Q are set accordingly. Then, the input data is amplified with a latch operation connected to the two respective outputs.

The hold stage occurs after the enabled stage is finished. In this step, the latch is disabled and the two output pins remain unchanged. Then, the last stage is the reset stage, where the reset pin R is activated and sets the two output pins (Q&Q ) to logic low.

The MC74AC573DTR2G logic latch’s features include low power consumption, high-speed performance, low noise, high switching frequency and thermal stability. The device is available in a variety of packages including VFQFPN, DIP, SOIC, WSON and SNUS.

In conclusion, the MC74AC573DTR2G is a versatile, low-cost device designed for use in digital systems and is suitable for a variety of applications in both industrial and consumer markets. It provides reliable performance, with low power consumption and high switching frequency, while also being thermally stable and producing very low noise levels.
