Functional Features

The SN74ABT574AZQNR is a D-type transparent latch with 3-state outputs. It can store and transfer data using clock pulses. The output enable (OE) pin allows the outputs to be put into a high-impedance state, enabling multiple devices to share a common bus.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - 3-state outputs for bus sharing

Disadvantages: - Limited voltage range (4.5V to 5.5V) - Not suitable for applications requiring higher voltage levels

Working Principles

The SN74ABT574AZQNR operates by latching the input data when the clock pulse (CP) is active. The latched data is then transferred to the outputs. The master reset (MR) pin resets the latch to its initial state. The output enable (OE) pin controls the output state, allowing the device to be connected to a shared bus.

Detailed Application Field Plans

The SN74ABT574AZQNR is commonly used in various digital systems where data storage and transfer are required. Some application fields include:

1. Microprocessors and microcontrollers
2. Data communication systems
3. Memory modules
4. Industrial automation
5. Automotive electronics
