Working Principles

The SN74LV574ARGYR is an octal D-type transparent latch that stores data based on clock pulses. When the latch enable (LE) signal is high, the input data is transferred to the outputs. The output enable (OE) signal controls whether the outputs are active or in a high-impedance state. This latch operates at low voltages, making it suitable for various electronic systems.

Detailed Application Field Plans

The SN74LV574ARGYR can be used in a wide range of applications, including:

1. Data storage and transfer systems
2. Microcontrollers and microprocessors
3. Communication equipment
4. Industrial automation
5. Automotive electronics
6. Consumer electronics
