Working Principles

The SN74ABT374ADW is an octal D-type flip-flop that stores and transfers data based on clock signals. When the clock enable (CE) input is high, the flip-flop is enabled, and data at the D0-D7 inputs is transferred to the Q0-Q7 outputs on the rising edge of the clock signal. The output enable (OE) input controls whether the outputs are active or in a high-impedance state. The clear (CLR) input resets the flip-flop to a known state when activated.

Detailed Application Field Plans

The SN74ABT374ADW is commonly used in various digital systems where sequential logic is required. Some application fields include:

1. Microprocessors and microcontrollers
2. Data storage systems
3. Communication equipment
4. Industrial automation
