• 3-State Outputs: The outputs can be disabled using the output enable (OE) input, allowing multiple devices to share a common bus.
• High-Speed Operation: The AHCT logic family ensures fast data transfer rates.
• Low Power Consumption: The IC operates at a low supply voltage and consumes minimal power.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data transfer. - Low power consumption makes it suitable for battery-powered devices. - 3-state outputs allow for bus sharing and reduce the number of required pins.

Disadvantages: - Limited voltage range (4.5V to 5.5V) may not be compatible with all systems. - Propagation delay time of 6 ns may affect timing-sensitive applications.

Working Principles

The SN74AHCT16373DGGR is a 16-bit transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data inputs (A1-A16) are transferred to the corresponding data outputs (O1-O16). The output enable (OE) input can disable the outputs, putting them in a high-impedance state.

The IC operates using AHCT logic, which ensures high-speed operation while consuming low power. It is designed to provide reliable data storage and transfer capabilities in various digital systems.

Detailed Application Field Plans

The SN74AHCT16373DGGR is commonly used in applications that require data storage and transfer, such as:

1. Microcontrollers: Used to store and transfer data between the microcontroller and external devices.
2. Memory Modules: Enables data transfer between memory modules and other components in computer systems.
3. Communication Systems: Facilitates data transmission between different communication modules.
4. Industrial Automation: Used in control systems to store and transfer data between sensors, actuators, and controllers.
