Functional Features

The SN74HCT374NSRG4 is an 8-bit D-type flip-flop with 3-state outputs. It has a clear input (CLR) to reset all flip-flops, and an output enable input (OE) to control the outputs. The flip-flop operates on positive-edge triggered clock inputs (CP). It is designed using high-speed CMOS technology, allowing for fast operation and low power consumption.

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Compact SOIC package - 3-state outputs provide flexibility in connecting multiple devices

Disadvantages: - Limited voltage range (2V to 6V) - Not suitable for applications requiring higher clock frequencies

Working Principles

The SN74HCT374NSRG4 operates as an 8-bit D-type flip-flop. When the clock input (CP) receives a positive-edge trigger, the data inputs (D0-D7) are latched and stored in the flip-flop. The stored data can be accessed through the corresponding output pins (Q0-Q7). The clear input (CLR) can be used to reset all flip-flops to a known state. The output enable input (OE) controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74HCT374NSRG4 is commonly used in various digital systems and applications, including: - Data storage and transfer - Address decoding - Register banks - State machine design - Parallel-to-serial and serial-to-parallel conversion
