Latches
What is a Latch?
A latch is a type of digital circuit that can store a bit of information. It's a basic memory element in sequential logic.
Types of Latches
- SR Latch (Set-Reset Latch): A simple latch that can be set or reset using two inputs.
- D Latch (Data Latch): A latch that stores the value of the input data when the clock signal is high.
How Latches Work
- Latches are bistable devices, meaning they can exist in one of two stable states.
- The state of the latch is determined by the input signals.
- Latches are often used in digital circuits to store temporary data or to implement more complex sequential logic.
Applications
- Memory Elements: Latches are used as basic memory elements in digital circuits.
- Sequential Logic: Latches are used to implement sequential logic circuits, such as counters and finite state machines.
- Digital Systems: Latches are used in a wide range of digital systems, including computers, smartphones, and other electronic devices.
