Functional Features

The SN74AHCT374DBRG4 is a high-speed, low-power 8-bit D-type flip-flop with 3-state outputs. It features a clear input (CLR) for resetting the flip-flop, an output enable input (OE) for controlling the output state, and a clock pulse input (CP) for synchronizing the data transfer.

The device operates on a supply voltage range of 4.5V to 5.5V and can handle a maximum operating frequency of 100MHz. It has a propagation delay time of 7ns, making it suitable for applications that require fast data storage and transfer.

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - 3-state outputs allow for bus sharing - Compact SOIC package for space-saving designs

Disadvantages: - Limited voltage range (4.5V to 5.5V) - Not suitable for high-frequency applications

Working Principles

The SN74AHCT374DBRG4 operates based on the principles of sequential logic. It uses D-type flip-flops to store and transfer data. The clock pulse input (CP) synchronizes the data transfer, ensuring that the data is captured at the rising edge of the clock signal.

When the clear input (CLR) is activated (LOW), all flip-flop outputs are reset to a low state. The output enable input (OE) controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74AHCT374DBRG4 can be used in various applications, including:

1. Data storage and transfer in microcontrollers and microprocessors
2. Address decoding in memory systems
3. Bus interface in communication systems
4. State machine implementation in digital systems
5. Register file design in computer architectures
