Functional Features

The SN74ABT374ANSR is a D-type transparent latch with 3-state outputs. It has the following functional features:

• High-speed operation: The flip-flop can operate at high clock frequencies, making it suitable for applications that require fast data storage and retrieval.
• Low-power consumption: The IC is designed to minimize power consumption, making it energy-efficient and suitable for battery-powered devices.
• 3-state outputs: The latch has 3-state outputs, allowing multiple devices to be connected to a common bus without interference.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data processing. - Low-power consumption prolongs battery life in portable devices. - 3-state outputs facilitate bus sharing in complex systems.

Disadvantages: - Limited voltage range (4.5V to 5.5V) may restrict compatibility with certain applications. - Propagation delay time of 2.8ns may not be suitable for ultra-high-speed applications.

Working Principles

The SN74ABT374ANSR operates based on the principles of digital logic. When the clock pulse (CP) input is triggered, the data inputs (D0-D7) are latched and transferred to the corresponding outputs (Q0-Q7). The output enable (OE) signal controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74ABT374ANSR can be used in various applications, including:

1. Data storage and retrieval systems
2. Address decoding circuits
3. Bus interface units
4. Memory modules
5. Microprocessor-based systems
